Examples of BoostingTermQuery

org.apache.lucene.search.payloads.BoostingTermQuery

The BoostingTermQuery is very similar to the {@link org.apache.lucene.search.spans.SpanTermQuery} exceptthat it factors in the value of the payload located at each of the positions where the {@link org.apache.lucene.index.Term} occurs.

In order to take advantage of this, you must override {@link org.apache.lucene.search.Similarity#scorePayload(byte[],int,int)}which returns 1 by default.

Payload scores are averaged across term occurrences in the document.

WARNING: The status of the Payloads feature is experimental. The APIs introduced here might change in the future and will not be supported anymore in such a case. @see org.apache.lucene.search.Similarity#scorePayload(byte[],int,int)


  public SpanQuery getSpanQuery(Element e) throws ParserException
  {
     String fieldName=DOMUtils.getAttributeWithInheritanceOrFail(e,"fieldName");
     String value=DOMUtils.getNonBlankTextOrFail(e);
      BoostingTermQuery btq = new BoostingTermQuery(new Term(fieldName,value));


      btq.setBoost(DOMUtils.getAttribute(e,"boost",1.0f));
    return btq;
