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 and not retrieval
- finds documents containing information but not retrieval
- (information and not retrieval) and WAIS
- finds documents containing WAIS, plus information but not retrieval
Note, please, that our search engine does not index resources, which are located at data bases, and resources of faculties (departments), which are located at individual servers.
