Synonym and Boolean Searches
If you combine a synonym search with a Boolean search, IDOL server obeys the Boolean rules while executing the synonym query. For example:
If the synonym file contains synonyms for the terms cat and dog, IDOL server returns only documents that contain both the term cat or one of the synonyms for cat and the term dog or one of the synonyms for dog. For example, documents that contain mouser and cur, cat and man's best friend, and so on.
