SpanQueryFilter
public class SpanQueryFilter extends SpanFilter (Code)
Constrains search results to only match those which also match a provided query. Also provides position information about where each document matches at the cost of extra space compared with the QueryWrapperFilter. There is an added cost to this above what is stored in a QueryWrapperFilter . Namely, the position information for each matching document is stored.

This filter does not cache. See the org.apache.lucene.search.CachingSpanFilter for a wrapper that caches.
