How it works: Altavista from Digital Equipment Corporation, is the latest spider search tool. You have access to all the words found in millions of Web pages. Altavista does not maintain a systematical index or catalogue. It also offers a full-text search of most newsgroups. Altavista provides extensive options on how to phrase a query.

Search Fields: Full-Web Page Contents (including URLs), Full-Text News Search Options: Substring/Word/Phrase, Multiple Keywords(OR)/Phrases, Wildcard(*) All lower case letters in a word indicate a case-insensitive match. But if you type any capital letters, you force an exact case match on the entire word.

How to use:
When in doubt, use lowercase text in your searches. When you use lowercase text, the search service finds both upper and lowercase results. When you use upper case text, the search service finds only upper case. Example: When you search for paris, you'll find Paris, paris, and PARIS in your result pages. However, when you search for Paris, you'll only see Paris in the result pages.

Including or excluding words: To make sure that a specific word is always included in your search topic, place the plus (+) symbol before the key word in the search box. To make sure that a specific word is always excluded from your search topic, place a minus (-) sign before the keyword in the search box. Example: To find recipes for cookies with oatmeal but without raisins, try recipe cookie +oatmeal -raisin.

Expand your search using wildcards (*): By typing an * at the end of a keyword, you can search for the word with multiple endings. Example: Try wish*, to find wish, wishes, wishful, wishbone, and wishy-washy.

AltaVista searches more than just text. Here are all of the other ways you can search on the net:

How it works: Excite is your guide to the Internet and more. It's your one-stop place for finding information of all kinds on the internet. NetSearch is comprehensive and detailed. It contains lots of information for you to search over -- Web pages, two weeks of Usenet news articles and classified ads. It's the best way to find exactly the information you're sure you want.

Excite also takes search technology one step further by using a unique concept-based approach to search. Like most search engines, Excite Search looks for documents containing the exact words you entered into the query box. But Excite goes further and also looks for ideas closely related to the words in your query.

Search Fields: Contents (Web Page), Usenet News and NewsGroups, Classified Advertisements. Does not read meta-tags (keyword, description, classification, author)

Search Options: Substring/Word/Phrase, Multiple Keywords (OR), Case In-Sensitive.
In advanced search, more options are available:Select Search Mode: Keyword Searching: Usual keyword searching. Concept-based Searching: Keyword searching can be very limiting, because of this restriction that the document actually contain one of the search-phrase words. Concept-Based searching finds what you mean, not just what you say.
Select View Modes : Grouped by Confidence (default) : List in order from highest calculated relevance down. Grouped by Site (Web pages/sites only) Represent which documents come from which Web sites, and how those documents are organized relative to each other at those sites.
How to use:
Use more than one word: Search for ideas and concepts instead of just keywords (be sure to use more than one word when you search). Excite uses Intelligent Concept Extraction (ICE) to find relationships that exist between words and ideas, so the results will contain words related to the concepts for which you're searching.

Try "More Like This": If you find that one of the Web results better describes what you are searching for, click on "More Like This" next to the title. Excite Search will then use that document as the basis for a new search to find more sites similar to the result you selected.

Be specific: Use specific words as opposed to general ones. For example, a search for "Lamborghini" will return more targeted results than a search for "sports cars."

Use "List by Web Site": Use the "List by Web site" function. Excite's list of search results may present several pages from the same site. When you click on the "List by Web site" link, your list will compress to show the names of the sites and relevant documents within them.

Try an Advanced Search: Use the "+" (plus) sign for words that your results MUST contain. Or use the "-" (minus) sign in your query to tell the search engine that your results should NOT contain a certain word. When using these options, do not leave any space between the sign and the word. (See below for more details on the Advanced Search feature.)

Try a "Power Search": Excite's Power Search feature makes it easy for you to perform an advanced search without having to use advanced syntax. You can also control how many search results are returned and what type of content you want to search against. For your search, choose among the following sources of information: World Wide Web, Selected Web Sites, Current News, Excite Germany, Excite France, Excite UK, Excite Sweden, and Usenet Newsgroups. Back to the top

Advanced Search Tips:
Search for exact phrases: When searching for phrases such as Better Business Bureau or San Francisco 49ers, enclose the phrase in quotation marks, i.e. "San Francisco 49ers". Using the quotation marks tells the search engine to find those words, in that specific sequence.

Try using plus (+) and minus (-) signs: These signs indicate which terms must (+) and must not (-) be present in the returned documents. When using these options, do not leave any space between the sign and the word.

Try using Boolean operators: Boolean operators tell Excite's concept-based search mechanism to turn off, allowing you to search for documents that contain exactly the words you are looking for. Boolean operators include AND, AND NOT, OR, and parentheses. These operators must appear in ALL CAPS, with a space on each side in order to work. -- Excite home -- home -- back -- top -- 19980722


How it works: The HotBot Search Engine (by Inktomi) is a Web indexer with a large database of more than 110 million documents. HotBot's pulldown menus and buttons let you modify or refine your search. Use these tools to narrow your search by placing more conditions on the query.

Search Fields: Contents, Titles, URLs/Links (HTML Addresses)
Search Options: Substring/Word, Multiple Keywords (OR), Case In-Sensitive, Limit Number of Matches, "+keyword" to indicate that 'keyword' must be in the document; "-keyword" to indicate that it must not. Limited Selection of Domain Root (only in Search for the Domain Name).

How to use:
1. Use at least two or three search terms. By using more keywords to narrow your search, you can locate documents that fit your information needs more precisely. Adding query terms is the easiest way to focus your search quickly - you can add terms directly to the text box on the results page. When using the default all the words setting, adding search terms narrows your results.

2. Be specific. Try to pick words that are unique to the topic you're investigating. If you're looking for information about the Virginia state motto, enter all three words in your search. If you enter Virginia motto, HotBot may give you pages that discuss mottos, but not the state motto.

3. Using all the words vs. any of the words. By default, HotBot displays documents containing all the words in your search query (Note: This is the equivalent of a Boolean AND search). By setting the main search pulldown menu to any of the words, you'll find documents that contain as few as one of your requested words (a Boolean OR search). This will increase the number of documents that are returned. HotBot's relevance ranking will automatically favor documents that contain the greatest number of your search words.

4. Use exact phrases. You can narrow your search by requesting that your search terms appear in order as an exact phrase. Select the exact phrase from the search pulldown menu, or simply enclose your phrase in double quotes (" "). For example, if you are looking for database administrators, search for these words as a phrase. This produces one-fifteenth as many matches. You can also mix phrases with single search terms in the search box, for example: "auto parts" BMW.

5. Give 'More Search Options' a spin. HotBot's detailed search is a powerful, but easy-to-understand, extension of the regular HotBot search interface. 'More Search Options' allows you to enter additional search terms, specify additional media types, and much more.

How it works:
InfoSeek offers a full text search service that makes finding information easy. This service is geared to professionals who want the latest and most in-depth information. InfoSeek's search robot regularly grabs text from sites across the Web, and puts them in a precise index. With InfoSeek you can search WWW Pages, Usenet News, Computer Magazines, Newspaper Newswires and Press releases, Company Profiles, Movie Reviews, Technical Support Databases, and much more.
Around since early 1995, Infoseek is well-known, well-reviewed and well-connected. The old "Infoseek Guide" index only had about 1 to 2 million URLs cataloged. In Fall 1996, the new service with 50 million URLs was introduced.
Infoseek runs a directory separate from its search engine. Sites are listed by topic, which are automatically generated using categorization software. Some sites also are listed with red check marks. These are Infoseek Select Sites, which have been reviewed and are recommended by Infoseek.

Search Fields: URLs, Contents, Usenet News
Search Options: Substring/Word/Phrase, Multiple Keywords (OR), Case Sensitive, Use double quotation marks (" ") around words which must appear next to each other. Use hyphens (-) around words which must appear within one word of each other. Use a plus sign (+) to identify terms that must appear in every document. Use a minus sign (-) to identify words or phrases that should not appear in any document. Use square brackets ([ ])around terms that should appear in the same area of a document.

How to use it: Follow these steps if you're new to the Web, or if you're an advanced user and would like a refresher course on making the most of your search and finding exactly what you need.

Step One: Type words likely to be found only in the documents you seek ruby slippers toto
Step Two: Identify phrases (a sentence, or a string of words) with quotation marks "ruby slippers" toto
Step Three: Identify proper names with capitalization "ruby slippers" Toto
Step Four: Identify required terms with a plus (+) sign +"ruby slippers" +Toto
Step Five: Identify undesired terms with a minus (-) sign +"ruby slippers" +Toto -"rock band"

How it works:
Lycos uses a spider to extract information from web sites regularly. The results are merged weekly into its systematic catalogue. Lycos includes Gopher and FTP addresses and gives you many search options, some of which appear in this search page. Lycos indexes non-text Internet resources including graphics, sounds, full-motion video and executable programs. For each document fetched, Lycos keeps the title, headings, subheadings, links, the 100 highest weighted words (using Tf*IDf weighting) and the first 20 lines.
Lycos provides the user with not only a list of all the sites a search has found, but also a ranking of the sites based on a "popularity" score for each of the sites. The popularity score for a particular site is calculated on the total number of other sites that contain links to that site. Lycos now offers the 'Lycos Hot Lists'; the most popular sites (based on number of link to a site) arranged by subject matter.
Around since May 1994, Lycos is one of the oldest of the major search engines. It began as a project at Carnegie Mellon University. The name Lycos comes from the Latin for "wolf spider."

Search Fields: URLs/Links (HTML Addresses, GOPHER(limited), FTP(limited)), Titles, Headings/SubHeadings, Contents (Keywords/First 20 lines)
Search Options: Substring/Word, Multiple Keywords (OR), Keywords Match Mode (AND/OR, Number or Type of keywords matches), Case In-Sensitive, Limit Number of Matches, Display Options: Standard, Summary or Detailed.

How to use it:
Looking for a Phrase (" ") .You'll often be searching for a word pattern that appears just as you've typed it. Examples are full names or phrases. You can tell Lycos to match your word pattern exactly by enclosing it in quotation marks. For example: "David Hasselhoff"

Excluding Words (-) You wouldn't know it by browsing the Web, but they still publish magazines that have nothing to do with computers. If you wanted to find information on magazines other than those related to computers, Lycos can help you do that. Use the minus (-) command in front of any word to screen out that word.

Requiring Words (+) The opposite of banning terms from your search results is requiring that certain words show up in the documents Lycos finds. Use the plus sign (+) before a "must-have" word that you want to include: Baywatch +Hasselhoff

How it works: The WebCrawler (now operated by America Online) gathers indexes of the total contents of documents. The database is indexed by content; that means that the contents of documents are indexed, including their titles and URLs.
The WebCrawler has different functions: It builds indices for documents it finds on the Web. The broad, content-based index is available for searching. It acts as an agent, searching for documents of particular interest to the user. In doing so, it draws upon the knowledge accumulated in its index and some simple strategies to bias the search toward interesting material.

Search Fields: Titles, URLs/Links (HTML Addresses), Contents. No meta-tags(keywords, descriptin, classification, author)
Search Options: Substring/Word, Multiple Keywords (AND/OR).

How to use it: You can customize WebCrawler to display your search results the way you want, if your browser supports cookies. You can view just the titles of the documents your search has returned, or see a short summary of each document: You can also select the number of results you would like to see on each page: 10 25 100 More Results

How it works: Yahoo is a massive, essential index of Web pages organized into categories. It features a hierarchically organised subject-oriented tree. It is probably the most complete hierarchical subject index on the Web: if it's not there, it probably doesn't exist... Yahoo does not rely on spiders, which constantly search the Web for new sites, but on the owners of Web sites who make their sites known to Yahoo. Before a site is accepted and categorised, it is reviewed by humans. If Yahoo can not find what you are looking for, it passes the query on to Altavista.
Around since late 1994, Yahoo is the oldest major web site directory. Yahoo is well-known, well-used and well-respected. It is also the largest directory (as opposed to search engine), listing 750,000 web sites, as of Dec. 1997.

Search Fields: Subjects, Titles, URLs (HTML Addresses), Comments.
Search Options: Substring/Word/Phrase, Multiple Keywords (AND/OR), Case Sensitivity, Limit Number of Matches.

How to use it:
After you have specified keyword(s) inside the query box and clicked on the search button, Yahoo (unless otherwise specified) will search through the four areas of its database for keyword matches. The four areas are:

Yahoo! first finds all the keyword matches and then sorts the results according to relevancy within each specific area. Yahoo! ranks results in the following manner: Tips for Better Searching:
Use Double Quotes Around Words that are Part of a Phrase. Example "great barrier reef"
Specify Words that Must Appear in the Results: Attach a + in front words that must appear in result documents. Example: sting +police
Specify Words that Should Not Appear in the Results Attach a - in front of words that must not appear in result documents. Example: python -monty

How it works: Yahooligans! is a searchable, browsable index of the Internet designed for Web surfers ages 7 to 12. We want it to be your Web surfing tool of choice.

Search fields: Yahooligans! search titles, URLs, and comments to find listings that contain all of your search words.

How to use it: Yahooligans! will not pay attention to case (e.g., "Mickey Mouse" is treated just like "mickey mouse") and it will stop after it finds100 matches. A search retrieves three different kinds of information:

How it works: McKinley's newly named Magellan Internet Directory contains listings for more than one million Internet resources (sites), with over 30,000 described, reviewed and rated resources, including Telnet, Gopher, FTP, World Wide Web sites, mailing lists and news groups. Each resource includes the site title, address (URL), hot links, keyword and audience descriptors, and a full text description of the resource and its contents.

Using their powerful search technology, researchers at The McKinley Group can explore vast portions of the Internet very rapidly. Acquired data are automatically sorted, abstracted and organized under Magellan's easy-to-use indexing structure. The information is divided into 15 major categories, ranging from Business & Economics to Sports & Recreation, with hundreds of subcategories.

McKinley uniquely couples machine intelligence with human intelligence to analyze and catalogue Internet resources. New sites are pored over by teams of subject matter experts and information technology specialists. Promising sites are reviewed, rated and described in Magellan. Ratings system is based on depth of content, ease-of-access, organization of information and currency.

You can explore Magellan in one of two ways: Browse the Magellan Categories OR Search the Magellan. Whichever kind of exploration you choose, Magellan will give you a "hit list" of up to 60 sites. For each hit it shows the name of the site, its rating, a partial or full description (depending on the length of the description), and a button labeled "summary."

Search Fields: Subjects, Titles, URLs (HTML Addresses), Contents.
Search Options: Substring/Word/Phrase, Multiple Keywords (OR), Boolean (AND/OR/NOT), NEAR/n, ADJ, Wildcard(*), Exact Match, Case In-Sensitive.

How to use:
In advanced search only : Regular Search or Concept Search: Concept search broadens a search by generating a list of terms related to your search word(s) and looking for them in addition to the word(s) you entered. This enables Magellan to find sites that do not contain the search words themselves, but may be relevant to the topic.

GoTo (has disappeared)

How it works: Only since early 1998 has GoTo replaced the World Wide Web Worm. It gathers information about documents/citations locations (URLs) and titles from Web servers rather than by spidering individual web pages. Compared to other Web search software, you might get fewer hits because GoTo only indexes hypertext references, the highlighted references to other pages or sites in Web documents. You may not get the most organized list from this type of search, but it's fast and does some things other searches won't: The GoTo provides a way to locate documents and citations. Each citation of a URL is cross-referenced with the document citing it (thus, a URL must be cited in some GoTo document page in order to be known to GoTo). Note! now URLs can be added manually. Any one URL may be cited in many different documents - GoTo will show them all.

How to use it: Search Options: Substring/Word, Multiple Keywords (AND/OR), Egrep Expression, Case In-Sensitive, Limit Number of Matches (".*" = Match Anything (Ex: FromHere.*ToHere) ; "\" = Quote (Ex: \.foo/\) -> Look for ".foo/")

Google searches over 1.3 million sites more quickly, to bring you the most relevant results. Google runs on a unique combination of advanced hardware and software. The speed you experience can be attributed in part to the efficiency of our search algorithm and partly to the thousands of low cost PC's we've networked together to create a superfast search engine.
The heart of our software is PageRank(TM), a system for ranking web pages developed by our founders Larry Page and Sergey Brin at Stanford University. And while we have dozens of engineers working to improve every aspect of Google on a daily basis, PageRank continues to provide the basis for all of our web search tools.

PageRank Explained
PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page's value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at more than the sheer volume of votes, or links a page receives; it also analyzes the page that casts the vote. Votes cast by pages that are themselves "important" weigh more heavily and help to make other pages "important."

Important, high-quality sites receive a higher PageRank, which Google remembers each time it conducts a search. Of course, important pages mean nothing to you if they don't match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all aspects of the page's content (and the content of the pages linking to it) to determine if it's a good match for your query.

Google's complex, automated methods make human tampering with our results extremely difficult. And though we do run relevant ads above and next to our results, Google does not sell placement within the results themselves (i.e., no one can buy a higher PageRank). A Google search is an easy, honest and objective way to find high-quality websites with information relevant to your search.

Basic Search
To enter a query into Google, just type in a few descriptive words and hit the 'enter' key (or click on the Google Search button) for your list of relevant results. Google uses sophisticated text-matching techniques to find pages that are both important and relevant to your search. For instance, when Google analyzes a page, it looks at what those pages linking to that page have to say about it. Google also prefers pages in which your query terms are near each other.

Automatic "and" Queries
By default, Google only returns those pages that include all of your search terms. There is no need to include "and" between terms.
For example, to plan a vacation to Hawaii, simply type: vacation Hawaii . To restrict a search further, just include more terms.

Google does support the logical "or" operator. To tell Google to look for pages containing either word A or word B, use a capitalized 'OR' between terms. For example, to search for a vacation in either London or Paris, just type vacation London OR Paris.

Stop Words
Google ignores common words and characters, known as stop words. Google automatically disregards such terms as "where" and "how," as well as certain single digits and single letters, because these terms rarely help narrow a search, and can slow down searching significantly. Use the "+" sign to include stop words in your search. Be sure to include a space before the "+" sign. You can also include the "+" sign in phrase searches.  For example, to search for Star Wars, Episode I, enter: Episode +I

See your search terms in context
Each Google search result contains one or more excerpt from the web page, which shows how your search terms are used in context on that page. Your search terms are bolded so you can tell at a glance whether the result is a page you want to visit.

To provide the most accurate results, Google does not use "stemming" or support "wildcard" searches. In other words, Google searches for exactly the words that you enter in the search box. Searching for "googl" or "googl*" will not yield "googler" or "googlin." If in doubt, try both forms: "airline" and "airlines," for instance.

Does capitalization matter?
Google searches are not case sensitive. All letters, regardless of how you type them, will be understood as lower case. For example, searches for "george washington", "George Washington", and "gEoRgE wAsHiNgToN" will all return the same results.

About the Open Directory Project
As the web grows, automated search engines and directories with small editorial staffs will be unable to cope with the volume of sites. The Open Directory Project's goal is to produce the most comprehensive directory of the web, by relying on a vast army of volunteer editors (In year 2000, there were over 31,000 editors; the directory covered over 2 million pages).
The web continues to grow at staggering rates. Automated search engines are increasingly unable to turn up useful results to search queries. The small paid editorial staffs at commercial directory sites can't keep up with submissions, and the quality and comprehensiveness of their directories has suffered. Link rot is setting in and they can't keep pace with the growth of the Internet. Instead of fighting the explosive growth of the Internet, the Open Directory provides the means for the Internet to organize itself. s the Internet grows, so do the number of net-citizens. These citizens can each organize a small portion of the web and present it back to the rest of the population, culling out the bad and useless and keeping only the best content.

You Can Make a Difference: Like any community, you get what you give. The Open Directory provides the opportunity for everyone to contribute.
Signing up is easy: choose a topic you know something about and join. Editing categories is a snap. We have a comprehensive set of tools for adding, deleting, and updating links in seconds. For just a few minutes of your time you can help make the Web a better place, and be recognized as an expert on your chosen topic.
Join the Open Directory Project: Find a category that you would like to maintain; Follow the Become an Editor link at the top of the category page. Note that there are no Become an Editor links on the top-level category pages; you should find a more specific category which interests you, and apply there.

Open Directory Search Guide
Simple search: Simple searches find entries that include all of the search terms. Search results are ranked and displayed 25 sites at a time. The sites that are displayed are grouped by their category. For example, a search on : C++ will return all the sites that have the word C++ in them. Searches with multiple terms will automatically insert an "and" between all the terms, so that only sites with all of the search words in them will be returned. For example, a search on: golf clubs will only return sites that have both golf and clubs in the sites name and description. Sites on "tennis clubs" or "golf balls" will not be displayed (unless they also mention golf and clubs).

Phrase Search:  Sometimes the order of the search terms matters. Using phrase searching can greatly reduce the number of sites that are matched by a search. For example if you searched for: "Tour de France" you would only get sites that had the three words: tour, de and France in them in that order.

Search Defaults: All searches use and as the default linking operator between all of the search terms. Thus searching for: red herring is the same as searching for: red and herring
For both of these searches, only those sites with "red" and "herring" in the site name or description will be returned. Sites that only mention "red" but not "herring" will not be displayed. To get sites with either "red" or "herring" use the keyword or. See the next section on using boolean operators.

Boolean Search: There are several boolean operators to choose from, they are: or, and, and andnot. Terms linked by the and operator will return only those sites that match all of the search terms linked by the and operator. This is the default, if you don't use any boolean operators, then only those sites that contain at least one occurrence of each search term will be returned.

Terms linked by the or operator will return those sites that match any of the search terms linked by or. For example: grey or gray and parrot
Terms linked by the andnot operator will exclude all sites that match the search term following the andnot. For example: random andnot house
will find sites about randomness, but exclude sites about the publisher, Random House.

Wildcard Search: The search can do some limited wildcarding. Specificly, wildcard completion. This is useful when you are trying to match a term that may or may not be plural or might have one of several verb tenses. For example if you wanted to find sites that had to do with bicycling you might use the following search: Bicycl* This would match sites on Bicycling, Bicycle, and Bicycles.
The search does not support arbitrary wildcards, so searches on "*cycling" or "Arch*ology" will not work.

Shorthand Search Terms: You can prefix search terms with "-" and "+" to force the exclusion or inclusion of that term. This is really just shorthand for using the andnot and and boolean operators. The following example will return all the sites on baseball, except those that mention "umpire."  +baseball -umpire
Note: You cannot begin a search with a "-" term. You must put some other search term first.
Complex Search: You can mix and match the above search methods to create very complex searches. This search will return all sites on Lego trains, but exclude all the links that mention Duplo: lego train* andnot duplo . This search will find references to racing, except those that are about racing cars or motorcycles:  racing -auto -car -motorcycle -road -nascar

What is MetaSearch? MetaSearch lets you search query many different search engines, while only having to type your query once. When you search, a "MetaSearch" bar appears at the bottom of the search results page. Clicking on one of the links will forward your query to another search engine, so you don't have to type it again.
