The text search engine allows queries to be formed from arbitrary Boolean
expressions containing the keywords "AND, OR, and NOT", and
grouped with parentheses. This will enable your to define exactly how you
want the the returned information filtered to result in precise
information.
For example:
- information retrieval
- finds documents containing 'information' or 'retrieval'
- information or retrieval
- same as above
- information and retrieval
- finds documents containing both 'information' and 'retrieval'
- information not retrieval
- finds documents containing 'information' but not 'retrieval'
- (information not retrieval) and wut2
- finds documents containing 'wut2', plus 'information' but not
'retrieval'
- web*
- finds documents containing words starting with 'web'
such as website.

Using these entry formats to
refine your search will improve the results you receive.
