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 selectionGroupQuery = createSelectionGroupQuery( selection );
          boolQuery.add( selectionGroupQuery, BooleanClause.Occur.MUST );
        }
      }
      if ( boolQuery.getClauses().length > 0 ) {
        this.facetFilter = new QueryWrapperFilter( boolQuery );
      }
    }
    return facetFilter;
  }
