opensearch Or Elasticsearch?

[Mister.T]

Hi,

Which should I install for enhanced search, opensearch or elasticsearch?

Thank you

Why isn't opensearch suitable?

On one of my client's systems, opensearch uses a tenth of the ram since we switched to elasticsearch. I wonder if it is the same case for Xenforo.
That may just be the app's characteristics, but it was drastic.

As someone running a site that needs 17gb of minimum memory to run elasticsearch, i'm curious to see if it'd use a lot less ram.
