<p>A system for retrieval of text includes a processor (10) which identifies grammar rules associated with text fragments of a text string that is retrieved from an associated storage medium, and retrieves text strings from the storage medium which satisfy the grammar rules. A display (34) displays retrieved text strings. A user input device (88) in communication with the processor enables a user to select text fragments of the displayed text strings for generating a query. The processor (10) identifies grammar rules associated with the user-selected text fragments and retrieves text strings from the storage medium which satisfy the grammar rules.</p> |
