I've got enterprise search up and running and indexed my documents. I've got basic search working but now I would like to get similar results to show on product pages. I know Elasticsearch has more_like_this api. Can this be used/accessed somehow in enterprise search?
The node api client doesn't seem to mention it at all.
Do I therefore have to use the regular Elasticsearch client? Can I just run it against the enterprise search api, or do I need to go direct to the elastic cluster? Is it fine to do that and access the underlying index or is it better to maintain a separate index in ES for it?
