Synonym and Boolean Searches
If you combine a synonym search with a Boolean search, Content obeys the Boolean rules while it processes the synonym query. For example:
action=Query&Text=cat+AND+dog&Synonym=True
If the synonym file contains synonyms for the terms cat and dog, Content 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.
