Examples of org.apache.lucene.search.FilteredQuery$LeapFrogScorer

org.apache.lucene.search.FilteredQuery
A Scorer that uses a "leap-frog" approach (also called "zig-zag join"). The scorer and the filter take turns trying to advance to each other's next matching document, often jumping past the target document. When both land on the same document, it's collected.
