[Parameter] Facet [Fields API Attribute Name] facet [Description] 
Enables a field's terms (words for text types, or exact value for "string" type) to be returned to the search client. In the default LucidWorks search interface, faceted fields are displayed and made navigable to constrain the search results. A field must be indexed to be facetable. This setting can be changed without reindexing, as it is used at query time only.
