# Synonym Search and Field Restrictions

You can use field restrictions within a synonym search to return only documents that contain the synonym in a specific field. For example:

    action=Query&Text=cat:Title&Synonym=True

If the synonym file lists synonyms for the term cat, Content returns only documents that contain the term cat or one of the synonyms for cat in their `Title` fields.
