Please don't post pictures of text or code. They are difficult to read, impossible to search and replicate (if it's code), and some people may not be even able to see them :slight_smile:

Is there anything in the Elasticsearch logs or slow log? What does hot threads show?

total_hits[1 hits], 
types[], 
stats[], 
search_type[QUERY_THEN_FETCH],
