The Search Engine allows queries to be formed from 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 storage | finds documents containing 'storage', plus 'information' but not 'retrieval' |
| web* | finds documents containing words starting with 'web' |
