Please provide a fully reproducible example that contains the exact HTTP calls to create the index plus mapping (especially for the date field), some sample documentsas well as the full query, so that others can reproduce your problem.

Also specifying your elastic stack version would help a lot. See also https://www.elastic.co/help
