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

    query = query.rewrite(reader);
    System.out.println("Searching for: " + query.toString(FIELD_NAME));
    TopDocs hits = searcher.search(query, 10);


    BoldFormatter formatter = new BoldFormatter();
    Highlighter highlighter = new Highlighter(formatter, new QueryScorer(
        query));
    highlighter.setTextFragmenter(new SimpleFragmenter(50));
    for (int i = 0; i < hits.scoreDocs.length; i++) {
      int docId = hits.scoreDocs[i].doc;
      Document hit = searcher.doc(docId);
