Why is a controlled vocabulary essential for searching?
With the wide variety of concepts and vocabulary used in the psychological literature, search and retrieval of records about specific concepts is virtually impossible without the controlled vocabulary of a thesaurus. This controlled vocabulary provides a way of structuring the subject matter in a way that is consistent among users (e.g., searching for Dysphoria, Melancholia, and Depression can all be achieved by searching the term “Major Depression”).
