Class MultiTermQuery.TopTermsBoostOnlyBooleanQueryRewrite
A rewrite method that first translates each term into SHOULD clause in a BooleanQuery, but the scores are only computed as the boost.
This rewrite method only uses the top scoring terms so it will not overflow the boolean max clause count.Inheritance
