         * - `scoring_boolean` - translates each term into boolean should and

         * - `constant_score_boolean` - same as `scoring_boolean`, expect no scores
         *  are computed.
         *
         * - `constant_score_filter` - first creates a private Filter, by visiting
         *  each term in sequence and marking all docs for that term
         *
         * - `top_terms_boost_N` - first translates each term into boolean should
         *  and scores are only computed as the boost using the top N
         *  scoring terms. Replace N with an integer value.
         *
         * - `top_terms_N` - first translates each term into boolean should
         *  and keeps the scores as computed by the query. Only the top N
         *  scoring terms are used. Replace N with an integer value.
         *
         * Default is `constant_score`.
         *
         * This is an advanced option, use with care.

         * `constant_score_filter` (synonyms for `constant_score`) have been removed
         * in elasticsearch 6.0.

         * @returns {WildcardQuery} returns `this` so that calls can be chained.
