Use more specific terms as opposed to general ones. A broad query like “perception” could retrieve anything from numerosity perception to extrasensory perception.
Search multiple phrases that could represent the topic (e.g., “guided imagery therapy” OR “directed reverie therapy”) or use the thesaurus to find the controlled vocabulary term.
Adjust your search strategy: If the results do not seem relevant, or if you are not satisfied with the size of the retrieval, try adding or eliminating concepts, changing the proximity operators, searching other fields, or using limits.
