Documentation on Kibana Visualisation - Query time & Request time

Can anyone point out the documents for Query time and Request time shown on the Inspect page in Kibana Visualisation?

Best that I can come across is on discussion forum What is Query Duration and Request Duration in Kibana? way back in 2016.

Any help would be appreciated.

If you hover over the question mark icons, there is a more detailed description for each of these. For your benefit, here is the description in the product:

Query time: The time it took to process the query. Does not include the time to send the request or parse it in the browser.

Request time: The time of the request from the browser to Elasticsearch and back. Does not include the time the requested waited in the queue.
