A “complete write-up” for a UUID isn’t possible without more context, because the same format is used in many systems—databases, distributed systems, log entries, session tokens, API request tracing, file identifiers, etc.
It looks like you’ve provided a (Universally Unique Identifier): 6c42db8e-eb92-4083-bbe6-90b62ffe025e
"query": "term": "request_id": "6c42db8e-eb92-4083-bbe6-90b62ffe025e"
SELECT * FROM orders WHERE id = '6c42db8e-eb92-4083-bbe6-90b62ffe025e';
