Examples of QueryWrapperFilter

org.apache.lucene.search.QueryWrapperFilter
Constrains search results to only match those which also match a provided query.
This could be used, for example, with a {@link TermRangeQuery} on a suitablyformatted date field to implement date filtering. One could re-use a single QueryFilter that matches, e.g., only documents modified within the last week. The QueryFilter and TermRangeQuery would only need to be reconstructed once per day.

Examples of org.apache.lucene.search.QueryWrapperFilter

        Query bq = new PrefixQuery( new Term( ArtifactInfo.GROUP_ID, term ) );
        // BooleanQuery bq = new BooleanQuery();
        // bq.add(new PrefixQuery(new Term(ArtifactInfo.GROUP_ID, term + "*")), Occur.SHOULD);
        // bq.add(new PrefixQuery(new Term(ArtifactInfo.ARTIFACT_ID, term + "*")), Occur.SHOULD);
        TermQuery tq = new TermQuery( new Term( ArtifactInfo.PACKAGING, "maven-plugin" ) );
        Query query = new FilteredQuery( tq, new QueryWrapperFilter( bq ) );


        FlatSearchResponse response = nexusIndexer.searchFlat( new FlatSearchRequest( query ) );


        Collection<ArtifactInfo> r = response.getResults();
