Yahoo Basic Search
http://search.yahoo.com/
Yahoo assumes as its default that multiple search terms are joined by the AND
operator, so that a search on the keywords [windows explorer] will find all the
webpages that contain both search terms.
Yahoo will not return any results if there is no webpage containing all the search
terms. Try this query to see what I mean:
rollerskate handshake buckyball
Unlike Google, Yahoo does not limit the number of search terms to 32
keywords. Yahoo will try to match all the keywords you enter.
Yahoo is not case sensitive.
Yahoo does not have true word stemming or truncation, i.e., searching for
variations of search terms. Normally, word stemming involves searching for plurals
and verb conjugations such as drink, drank, drunk. However, Yahoo's word
stemming is not consistent and somewhat confusing. For example, stemming works
with some words but not with others, i.e., a search on [child] will not find children; a
search on [drink] will find drinks but not drinking or drunk. Users should search on all
variations of a term, including plurals, and not rely upon the automatic but
inconsistent stemming feature. However, there is a Yahoo hack to disable word
stemming.
Yahoo automatically clusters search results. If you want to see more pages from
a specific site, simply select that link following the uri of the result.

Yahoo permits the use of boolean operators in simple search. The operators
must be capitalized. Yahoo Search will run full nested boolean queries (those using
parentheses), such as:
[cardinals AND (bird OR catholic) AND NOT (baseball OR football)]
