<DD>Sets the boost factor hits on this field.

This product is then multipled by the value <A HREF="../../../../org/apache/lucene/search/Similarity.html#lengthNorm(java.lang.String, int)"><CODE>Similarity.lengthNorm(String,int)</CODE></A>, and rounded by <A HREF="../../../../org/apache/lucene/search/Similarity.html#encodeNorm(float)"><CODE>Similarity.encodeNorm(float)</CODE></A> before it is stored in the index.
