Is there an error, or is the issue that the query is slow? I suspect that if you removed the ORDER BY the query would execute quickly.

Ultimately the expression pushed down to ES might be slow for ES to execute. Can you share the query plan and we can help take a closer look?

In addition, you might consider using Data Reflections to speed up your analytical queries on ES: https://docs.dremio.com/acceleration/reflections.html
