Does ElasticSearch have a size limit on its JSON queries?

e.g. If I filter using ids, and I build up a list of 1 million+ ids, will the request be rejected?

In theory there must be a ceiling. But I can't find any documentation on it.

    Which API are you asking for ? If you are going to use search API with terms query there is a limit of 65,536 terms elastic.co/guide/en/elasticsearch/reference/current/… Commented Feb 15, 2021 at 21:40
  • Actually this is perfect. Yes I'm using the search API with terms. Commented Feb 16, 2021 at 12:01
