Property LowFreqMinimumNumberShouldMatch

Gets or Sets a minimum number of the low frequent optional BooleanClauses which must be satisfied in order to produce a match on the low frequency terms query part. This method accepts a float value in the range [0..1) as a fraction of the actual query terms in the low frequent clause or a number >=1 as an absolut number of clauses that need to match.

By default no optional clauses are necessary for a match (unless there are no required clauses). If this method is used, then the specified number of clauses is required.
