Received ban for the parent , reason: [by user request]

I am experiencing the follwoig BUG/WARN when sporadically our searches appear to not be returning when these messages are seen.
They all seem to begin with the "Received ban for the parent" message. Other times the same searches return fine from the same index.
Current ELK version is 7.6.2
I was hoping that someone has seen or knows what could be causing this. Any insight would be greatly appreciated.

The search fails with cause:
