Deprecated.
Since max_optimization optimization landed in 7.0, normal MatchQuery will achieve the same result without any configuration.
CommonTermsQuery query is a query that executes high-frequency terms in a optional sub-query to prevent slow queries due to "common" terms like stopwords. This query basically builds 2 queries off the #add(Term) added terms where low-frequency terms are added to a required boolean clause and high-frequency terms are added to an optional boolean clause. The optional clause is only executed if the required "low-frequency' clause matches.

    • highFreqOperator

      public CommonTermsQueryBuilder highFreqOperator​(Operator operator)
      Deprecated.
      Sets the operator to use for terms with a high document frequency (greater than or equal to cutoffFrequency(float). Defaults to AND.

      Deprecated.

    • lowFreqOperator
