The search engine features chart below is designed primarily for users of search engines. It summarizes key search commands and search assistance features. These are described more fully on the Search Engine Math, Power Searching For Anyone and Search Assistance Features pages. You may also find information on the Search Engine Features For Webmasters page to be of interest. See the Major Search Engines page for links to the services listed below.

NOTE: By default, all the major search engines named above will match ALL of the terms you enter into a search box. This means that it is not necessary to use the + symbol in front of a particular word, though it won't hurt if you do so.

Power Searching Commands
(See Power Searching For Anyone for more details)

This section is being updated to cover the major crawler-based search engines of AllTheWeb, AltaVista, Google, Inktomi and Teoma. These crawlers also provide results to other search engines, so you may find commands on them work with their partners. Major partnerships are as follows: AllTheWeb (Lycos), Google (AOL Search, Yahoo), Inktomi (HotBot), MSN Search (Inktomi), Teoma (Ask Jeeves)

NOTE: The commands above are primarily useful when dealing with crawler-based search engines. "None" indicates any crawler-based or human-powered search engine that creates its own listings but which does not provide a particular command for searching within those listings. It may also indicate a portal that that outsources for its listings and which lacks a single command to work across the multiple datasets it uses.
