+The <<esql,{esql}>> async query stop API is used to manually stop an async query. Once the stop command is issued,
 the query stops processing new data and returns the results that have been already processed. Note that due to the pipelined

 The results are returned in <<esql-query-api-response-body,the same format>> as for
