A brief explanation of the query language is available, along with examples.

Query Language

The text search engine allows queries to be formed from arbitrary Boolean expressions containing the keywords AND, OR, and NOT, and grouped with parentheses. 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 WAIS

finds documents containing 'WAIS', plus 'information' but not 'retrieval'



web*

finds documents containing words starting with 'web'
