I think it's the same question as in [How to convert and use an API query into equivalent SQL query in a java class](https://discuss.elastic.co/t/how-to-convert-and-use-an-api-query-into-equivalent-sql-query-in-a-java-class/230026) Please be patient in waiting for responses to your question and refrain from pinging multiple times asking for a response or opening multiple topics for the same question.
