Live Basic Search<br />

http://www.live.com/<br />

Live Search has changed little about its basic search internals in terms of how it<br />

handles queries and <strong>the</strong> number of basic search options.<br />

Live Search assumes as its default that multiple search terms are joined by <strong>the</strong> AND<br />

operator, so that a search on <strong>the</strong> keywords [windows explorer] will find all <strong>the</strong><br />

<strong>web</strong>pages that contain both search terms.<br />

Live Search recognizes double quotes as enclosing a phrase.<br />

Live Search will not return any results if <strong>the</strong>re is no <strong>web</strong>page containing all <strong>the</strong><br />

search terms. Try this query to see what I mean:<br />

[rollerskate handshake specktioneer]<br />

Unlike Google, Live Search does not limit <strong>the</strong> number of search terms to 10<br />

keywords. Live will try to match all <strong>the</strong> keywords you enter.<br />

Live Search is not case sensitive.<br />

Live Search does not offer any word stemming or truncation, i.e., searching for<br />

variations of search terms. A search for [child] will not find [children].<br />

Live Search automatically clusters search results. If you want to see more pages<br />

from a specific site, simply select <strong>the</strong> link following <strong>the</strong> uri of <strong>the</strong> result.<br />

Live permits <strong>the</strong> use of nested boolean queries in simple search. The operators<br />

must be capitalized. Live Search will run nested boolean queries (those using<br />

paren<strong>the</strong>ses), such as:<br />

[cardinals AND ("st louis" OR arizona) NOT (bird OR catholic)]<br />

Live Search will ignore stop words, i.e., commonplace words, if <strong>the</strong> query<br />

contains non-stop words; <strong>the</strong> query [to be or not to be] will only search for <strong>the</strong> term<br />

"not." However, you can search on any single letter or number by itself, e.g., [1]. You<br />

can also force Live Search to look for stop words ei<strong>the</strong>r by enclosing <strong>the</strong> query in<br />

double quotes ["to be or not to be"] or by placing a plus sign in front of <strong>the</strong> stop word,<br />

e.g., [+1 number] or [+to +be +or +not].<br />

O<strong>the</strong>rwise, it is unnecessary to use <strong>the</strong> plus sign (+) with any terms because by<br />

default Live Search searches for all keywords. However, many times searchers need<br />

to exclude certain terms that are commonly associated with a keyword but irrelevant<br />

to <strong>the</strong>ir search. That's where <strong>the</strong> minus sign (-) comes in. Using <strong>the</strong> minus sign in<br />

front of a keyword ensures that Live Search excludes that term from <strong>the</strong> search. For<br />

example, <strong>the</strong> results for <strong>the</strong> search ["pearl harbor" -movie] are very different from <strong>the</strong><br />
