How To Search/Yahoo

Yahoo! Search

  • Purpose: "Our mission is to be the most essential global Internet service for consumers and businesses." [1]
  • Audience: All Internet users.
  • Scope: The Internet. All documents that Yahoo's web crawling software can process.
  • Refresh Rate: Constant
  • Other Information: It is important to differentiate between Yahoo! Search, which this page is about, and the Yahoo web site directory. Yahoo! Search is a fully automated Internet search engine. (Although it seems to incorporate a few "Yahoo! Shortcuts," listed below, that may be human indexed.) On the other hand each web page in the web site directory is categorized by humans, it is not automated.

Search ShortcutsEdit

Yahoo refers to the following as Yahoo! Shortcuts. Some have yet to be listed in this wikibook.

When typing a shortcut it looks just like a normal word search. The difference shows up when the search results appear. Below advertisements and above the numbered search results there will be an entry with a red Yahoo Y next to it. This shortcut entry may provide an answer, if using the calculator or dictionary, or it may link to further pages with the answer.


Shortcut Description Example Further Information

Definitions Defines words define numeral define numeral

Other FeaturesEdit

Yahoo! Search also allows a number of searches which can only be done using templates on their web pages. These can be found in the advanced search. These include file format (doc, html, pdf, ppt, rss, txt, xls), search language, safesearch filter, and country.

Other features not directly impacting search results include number of results listed per page.
