The following information is copied from the FreeFind web site
for your convenience:
By default the search engine tries to locate pages which have
exact matches for all of the words entered in your search query.
If that fails, it then tries to locate pages which contain any
words in your search query. If that happens a short message is
displayed at the top of the search results indicating this has
been done.
In addition, there are several ways to modify the default
search behavior.
- + and - qualifiers
- If you prepend a word with + that word is required to be
on the page. If you prepend a word with - that word is required
to not be on the page. Example: +always -never
- * wildcard
- If a query word ends with a * all words on a page which start
the same way as that query word will match.
Example: gift*
- ? wildcard
- If a query word contains a ? any character will match that
position. Example: b?g
All of these techniques can be combined: +alway* -ne??r*
