Draw attention to transport port in remote cluster documentation

[akki]

It would be nice to emphasize on the fact that remote cluster connections require another port (not the one Elasticsearch is usually available on).

I am not very clear on how these ports are different but after struggling a lot to set up a cross-cluster search I realised that Elasticsearch exposes port 9300 as well for some things and it is 9300 that needs to be mentioned in the seeds.

I do see that it is being used in the example here - https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-remote-clusters.html. But I didn't realise that 9300 was being used instead of 9200 intentionally until I read this comment from Mr. javanna.

The documentation explicitly says that:
All the communication required between different clusters goes through the transport layer.
The linked documentation explains what the transport module is and how the communication is handle in this module. However I guess that it would help to repeat that the transport port should be used on the first mention of seeds in the snippet examples. Would you be interested to provide a patch for this ?

@jimczi I admit I did somehow skipped going through the transport layer link when it was mentioned in the docs.

Do you mean something like adding another info point with the snippet (see attached picture)? I think that would is a good idea.

I would be happy to send a patch but it would quite helpful for me if you could tell me where these docs reside (Elasticsearch docs code seems a bit overwhelming to me as a beginner 😅).

Thanks for your quick reply!

Yes, if you think it is helpful ;)

You can find this doc here.
