: Basically, what is the difference between issuing a facet field query : that returns facets with counts, : and a query with term vectors that also returns document frequency : counts for terms in a field?
The FacetComponent generates counts that are relative the set of documents that match your query, so if you search for "jimbo" and 1034 docs match, then your facet counts will tell you how many of those 1034 docs match each of the facet constraints. The TermsComponent generates counts that tell ou about the raw terms in the index -- you don't even need to have a search (or a doc set) to use the TermsComponent, it just gives you raw data from the index. (that's why the "/terms" handler in the example Solr 1.4 configs doesn't even include the "query" component, and the examples using hte TermsComponent never mention a "q" param) -Hoss
