The search box for the FAQs have the option of using a regular expression or using MySQLs boolean mode full text searches.
Regular Expression Search
To implement the regular expression search, make sure the "regular expression" check box is selected. In the "Search" box you can use the patterns shown in the table below.
|.||Matches any single character|
|||Matches any of the characters (or range of characters) in the brackets.|
|*||Matches zero or more instances of the preceding character.|
|^||Start of the text being scanned.|
|$||End of the text being scanned.|
The results are sorted according to the topic index.
Boolean Mode Full Text Search
To implement the boolean mode full text search, make sure the "regular expression" check box is not selected. In the "Search" box you can use the operators listed in the table below:
|+||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.
