I'm new to Elasticsearch, using version 7.1.2. I am setting up an index which contains time-stamped records for users. I would like to find out how to search for all users who are not active (i.e. have no records) over a period of time. I can create another index which contains a list of all users, but am not sure how to combine the two in a query and search for null matches.
