  "fq" stands for Filter Query.
  
- This parameter can be used to specify a [:SolrQuerySyntax: query] that can be used to restrict
the super set of documents that can be returned, without influencing score.  It can be very
useful for speeding up complex queries since the queries specified with fq are cached independently
from the main query.  This assumes the same Filter is used again for a latter query (i.e.
there's a cache hit)
