What is the effect of circuit breakers limit on search queries

[md2 (MD)]

Hi, I am wondering what happens to the queries that hit the circuit breakers memory limit, are they discarded completely and lost forever? What is the recommended method to monitor these queries?

Does this entry from the logs indicate certain query hit the limit and was discarded?

They are cancelled by Elasticsearch and a response is sent to the client that requested it, so it's up to that client to take appropriate action.

Yes.
