+  Use \`MATCH_PHRASE\` to perform a [\`match_phrase\`](https://www.elastic.co/docs/reference/query-languages/query-dsl/query-dsl-match-query-phrase) on the
+  specified field.
+  Using \`MATCH_PHRASE\` is equivalent to using the \`match_phrase\` query in the Elasticsearch Query DSL.
+
+  MatchPhrase can be used on [text](https://www.elastic.co/docs/reference/elasticsearch/mapping-reference/text) fields, as well as other field types like keyword, boolean, or date types.
+  MatchPhrase is not supported for [semantic_text](https://www.elastic.co/docs/reference/elasticsearch/mapping-reference/semantic-text) or numeric types.
+
+  MatchPhrase can use [function named parameters](https://www.elastic.co/docs/reference/query-languages/esql/esql-syntax#esql-function-named-params) to specify additional options for the
+  match_phrase query.
+  All [\`match_phrase\`](https://www.elastic.co/docs/reference/query-languages/query-dsl/query-dsl-match-query-phrase) query parameters are supported.
+
+  \`MATCH_PHRASE\` returns true if the provided query matches the row.
