Domain specific vocabularies exist which describe terms and relationships in a machine readable format.  These terms could be used to aid indexing and help users refine their searches.

''Note: This feature is based on an early analysis of the [http://en.wikipedia.org/wiki/AGROVOC AGROVOC] vocabulary in [http://www.w3.org/2004/02/skos/ SKOS] format, and is subject to change and refinement.''

== Requirements ==

* When indexing, look up subject terms in the vocabulary and cross-index with equivalent terms.  For example, if "field" is defined as equivalent to "plot", resources tagged with "field" will be indexed with both "field" and "plot".
* When displaying search results with subject refinements, offer broader and narrower refinements for the search terms.  For example, if a search is filtered with "subject:field", the interface might offer "See more: search for subject:soil" and "See fewer: search for subject:furrow"
