                 URL: https://issues.apache.org/jira/browse/LUCENE-960
             Project: Lucene - Java
          Issue Type: Improvement
          Components: Search
            Reporter: Grant Ingersoll
            Priority: Trivial


Similar to the QueryFilter (or whatever it is called now) the SpanQueryFilter is a regular
Lucene Filter, but it also can return Spans-like information.  This is useful if you not only
want to filter based on a Query, but you then want to be able to compare how a given match
from a new query compared to the positions of the filtered SpanQuery.  Patch to come shortly
also contains a caching mechanism for the SpanQueryFilter
