OVERVIEW
A thesaurus is an example of a controlled vocabulary which is used to classify a body of knowledge. The index terms of a thesaurus are predefined and are in turn organised in a hierarchy of broader and narrower terms. A polyhierarchical thesaurus allows narrower terms to link to more than one broader term. Subject thesauri exist in many subject domains.
Why use a thesaurus?
By using a controlled vocabulary you are increasing the chances that a user will retrieve relevant items in their search. By including synonyms as related terms the search will retrieve more items that a single unrelated search term e.g. making a link within the thesaurus between "mental health" to include "mental illness".
Care must be taken to be consistent in the indexing and that the right terminology is used that the audience is familiar with and will use themselves.
