MultiTermRewriteMethod

By default, it uses CONSTANT_SCORE_AUTO_REWRITE_DEFAULT when creating a prefix, wildcard and range queries. This implementation is generally preferable because it a) Runs faster b) Does not have the scarcity of terms unduly influence score c) avoids any exception due to too many listeners. However, if your application really needs to use the old-fashioned boolean queries expansion rewriting and the above points are not relevant then use this change the rewrite method.

Declaration
MultiTermQuery.RewriteMethod MultiTermRewriteMethod { get; set; }
Property Value
Type Description
Lucene.Net.Search.MultiTermQuery.RewriteMethod
