Some of the docs in an index having the time filter is null/none/no value. How to create a GET query to filter out those documents? ---

you can use the `exists` query, see [https://www.elastic.co/guide/en/elasticsearch/reference/7.4/query-dsl-exists-query.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.4/query-dsl-exists-query.html) Use a `bool` query with a `must_not` clause, that contains the exists query, basically searching for a document where this field does not exist. --Alex ---
