Examples of QueryScorer

org.apache.lucene.search.highlight.QueryScorer
{@link Scorer} implementation which scores text fragments by the number ofunique query terms found. This class converts appropriate {@link Query}s to {@link SpanQuery}s and attempts to score only those terms that participated in generating the 'hit' on the document.
