/**
* The BoostingTermQuery is very similar to the {@link org.apache.lucene.search.spans.SpanTermQuery} except
* that it factors in the value of the payload located at each of the positions where the
* {@link org.apache.lucene.index.Term} occurs.
* <p>
* In order to take advantage of this, you must override {@link org.apache.lucene.search.Similarity#scorePayload(String, byte[],int,int)}
* which returns 1 by default.
* <p>
* Payload scores are averaged across term occurrences in the document.
*
* @see org.apache.lucene.search.Similarity#scorePayload(String, byte[], int, int)

* @deprecated See {@link org.apache.lucene.search.payloads.PayloadTermQuery}
