Hello, I had a bug with pipeline, and my messages are not routed to right stream.
May I manually move the messages from a Stream to another one ? (the streams are linked to same indice)
According to the documentation, there are no tool built for what you are asking.
I understand for tool built, but maybe with an elasticsearch query ?
Possibly - but likely better queried in Elasticsearch forums… 
I don’t know Elasticsearch to that depth…yet.
