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.

Examples of org.apache.lucene.search.highlight.QueryScorer

    ScoreDoc[] hits = collector.topDocs().scoreDocs;
    //setsback to action
    objectsToReturn.put("hits", hits);
    
    //highlighter
        Highlighter highlighter = new Highlighter( new SimpleHTMLFormatter(), new QueryScorer(andQuery));
    if(hits != null) {
      logger.debug("hits size: " + hits.length);
            for(int i=0; i<hits.length; i++) {
            ScoreDoc hit = hits[i];
            Document doc = searcher.doc(hit.doc);
