Each term may be preceded by the standard Boolean operators not,
and, or or. If you search for "dogs not pizzas",
you'll find all documents containing the word "dogs" except
those documents which also contain the word "pizzas". If you
type in "and hot and dog and pizzas", you'll find only those
documents which contain all three search terms. The default value is or.
Thus, a search for "hot dog pizzas" would return pages with at least
one of the three terms.
Shorthand notation works too. A search on "dogs -hot" is equivalent to
the first example, and "+hot +dog +pizzas
" will return the same documents as the second.
To group a collection of words, use quotes. For example, the query "Microgetics
Corporation" (quotes included) would not generate a hit from
"Microgetics Inc.". Without quotes, the sentence would count. Boolean operators
can also act on quotations: a search on '+the +kitten not "the kitten"'
would return only those documents where "the" and "kitten
" appear separately.
Intermediate Search finds words, not strings. A search for "in" would
turn up only that word, not "bin", "inside", or "acquaintance".
To perform a string search, preface your term with the dollar sign - a query on
"\$in" would find all words lists above. Note that more complex
wildcard searches using the asterisk are not
permitted. Including the asterisk in your query will return a list of all
files, but that's its only function.
