> A filter query retrieves a set of documents matching a query from the filter cache. Since scores are not cached, all documents that match the filter produce the same score. Cached filters will be extremely fast when they are used again in another query.
> Filter Query Example:
> {code}
> description:HDTV OR filter(+promotion:tv +promotion_date:[NOW/DAY-7DAYS TO NOW/DAY+1DAY])
> {code}
> The power of the filter() syntax is that it may be used anywhere within a lucene/solr query syntax. Normal fq support is limited to top-level conjunctions.
