The keyword search box for some of the site pages use MySQL’s boolean mode full text searches. In the “Keywords” box you can use the operators listed in the table below:

Boolean Mode Operators
Operator	Description
`+`	The word must be matched.
`-`	The word must not be matched.
`~`	Invert the word's relevance.
`<`	Decrease word's contribution to the overall relevance of the match.
`>`	Increase word's contribution to the overall relevance of the match.
`*`	Comes after the word it modifies and works like a wildcard.
`()`	Groups words into subexpressions.

The results are sorted according to relevance. Other punctuation is ignored or treated as a word boundary.
