org.apache.lucene.search.MultiTermQueryWrapperFilter<Q>
public class MultiTermQueryWrapperFilter<Q extends MultiTermQuery>
A wrapper for MultiTermQuery, that exposes its
functionality as a Filter.
MultiTermQueryWrapperFilter is not designed to
be used by itself. Normally you subclass it to provide a Filter
counterpart for a MultiTermQuery subclass.
For example, TermRangeFilter and PrefixFilter extend
MultiTermQueryWrapperFilter.
This class also provides the functionality behind
MultiTermQuery.CONSTANT_SCORE_FILTER_REWRITE;
this is why it is not abstract.

If you re-use the same filter instance for another
search, be sure to first reset the term counter
with clearTotalNumberOfTerms().

public DocIdSet getDocIdSet(IndexReader reader)
throws IOException
