+  A boosted term query - no analysis is done of the child text. Also a span member.
+
+  (Text below is copied from the javadocs of BoostingTermQuery)
+   
+  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.
+
+  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.
+
+  Payload scores are averaged across term occurrences in the document.
+
+  @see org.apache.lucene.search.Similarity#scorePayload(String, byte[], int, int)
