[Enhancement]: Support for additional search engine backends beyond Meilisearch

[arthurian]

Hello,

I'm interested in exploring the possibility of extending this project to support additional search engine backends beyond the current Meilisearch integration.

While Meilisearch works well for many use cases, adding support for other search engines (like Elasticsearch, Opensearch, Solr, Algolia, or Typesense) could:

• Provide flexibility for users with existing search infrastructure
• Address different scaling needs and use cases
• Allow leveraging specific features unique to other search engines
• Broaden the project's adoption by catering to diverse preferences and requirements

Before I consider contributing to this effort, I'd like to understand:

• Is this direction aligned with the project's vision?
• Has this been considered previously?
• Is anyone working on this currently, or if not, would there be interest in PRs that implement an abstraction layer for multiple search backends?

I'd be happy to discuss implementation approaches if there's interest in this enhancement. I would also be more than happy to support any existing efforts in this area. Thanks!

Hi @arthurian 👋

This would be great, especially Elasticsearch which is quite a mature technology.

Hi @danny-avila!

Great! We would be interested in Elasticsearch too, or perhaps Opensearch, since that would integrate nicely with our existing infrastructure around LibreChat.

I would love to see this as well - especially when we can have a possibility to plug in various search engines - in our case it would be more a cloud provider offering...

+1 on this, OpenSearch and ElasticSearch are very popular search engine, allowing LibreChat to work with them would be super.
