Examples of PayloadTermQuery

org.apache.lucene.search.payloads.PayloadTermQuery
This class is very similar to {@link org.apache.lucene.search.spans.SpanTermQuery} except that it factorsin the value of the payload located at each of the positions where the {@link org.apache.lucene.index.Term} occurs.
NOTE: In order to take advantage of this with the default scoring implementation ( {@link DefaultSimilarity}), you must override {@link DefaultSimilarity#scorePayload(int,int,int,BytesRef)}, which returns 1 by default.
Payload scores are aggregated using a pluggable {@link PayloadFunction}. @see org.apache.lucene.search.similarities.Similarity.SimScorer#computePayloadFactor(int,int,int,BytesRef)

      TopDocs topDocs = searcher.search(directQuery, 10);
      System.out.println("Number of matching docs: " + topDocs.totalHits);
      ScoreDoc doc1 = topDocs.scoreDocs[0];
      System.out.println("Doc: " + doc1.toString());
      System.out.println("Explain: " + searcher.explain(directQuery, doc1.doc));
      Query payloadQuery = new PayloadTermQuery(new Term("title", "London"), new MaxPayloadFunction());
      topDocs = searcher.search(payloadQuery, 10);
      System.out.println("Number of matching docs: " + topDocs.totalHits);
      ScoreDoc doc2 = topDocs.scoreDocs[0];
      System.out.println("Doc: " + doc2.toString());
      System.out.println("Explain: " + searcher.explain(payloadQuery, doc2.doc));
