I have a query that may need to run on multiple threads in parallel to speed the running up. But I don't know will Elasticsearch execute one query on multiple threads if possible by default or I need to use multiple threading client to send requests to Elasticsearch. ---

A query will be split up into shard-level queries. The shard-level queries will be executed concurrently. I hope that answers your question. ---
