Each keyword may be separated by the standard Boolean operators not, and, or or. If you enter windows not 2000, you'll find all documents containing the word "windows" except those documents which also contain the word "2000". If you type in and windows and XP and ME,only the documents which contain all three terms will be returned. The default value is or. Thus, a search for "windows XP ME" would return pages with at least one of the three terms.
Case Sensitivity: If a search term has at least one capital letter, like Unix, the search will be case sensitive with respect to that word - that is, only documents containing Unix will be found. Lowercase words like unix will generate hits from unix, Unix, or UNIX.
Using shorthand notation: A search on windows -XP is equivalent to windows not XP, and +windows +pc it the same as and windows and pc.
Grouping a collection of words: To group a collection of words, use quotes. For example, the query "Windows Unix" would return a document with Windows Unix connectivity and not generate a hit from Windows connectivity with Unix. Boolean operators can also act on quotations: a search on +windows +pc not "windows pc" would return only those documents where windows and pc appear separately.
Searching for Strings: A search for in would return only documents containing in. To find documents with words containing in like "bin", "inside", or "acquaintance" perform a string search. To perform a string search, preface the term with the dollar sign. A query on "\$in" finds all words above.
Note: Wildcard searches using the asterisk are not used. Including the asterisk in a query will return a list of all files.
