@Deprecated
public class ExtendedCommonTermsQuery
extends CommonTermsQuery

Deprecated.

Since max_optimization optimization landed in 7.0, normal MatchQuery will achieve the same result without any configuration.

Extended version of CommonTermsQuery that allows to pass in a minimumNumberShouldMatch specification that uses the actual num of high frequent terms to calculate the minimum matching terms.
