I'm getting a lot of ResourceNotFoundExceptions when using percolator queries, and I cannot seem to fully understand why... So the document that is reported to be missing in an index, indeed is not there, but I don't understand why is then this exception thrown? Is it unexpected to call a percolator query on a document that is not yet indexed? Should the default behavior be more in line of returning an empty result? Or am I missing something?
The full stack trace is:
org.elasticsearch.transport.RemoteTransportException: [WTHMxFY][10.10.20.130:9300][indices:data/read/search[phase/query]]

We are at the moment using an outdated ES 5.5.2, but it is the plan to update soon.
