Meilisearch

Meilisearch is a best of breed state of the art full test search engine written in Rust, fully Open Source, but with a commercial offering. It is evidently a great replacement for Elastic when you need fulltext - but even more so of Algolia. And coupled with something like Crawl4AI or one of the other crawlers it can give you huge mileage as a general purpose search engine. Simple. Fast. Robust. Conflict of interest statement: I have none. It's just an incredibly lovely piece of software. The API is pretty, usable and very easy to understand and the client libs are top-notch too (full disclosure: I only used the Golang, Python and JS ones). For the vector retrieval side of the house: with Meilisearch it is basically a setting on an Index. That’s it. You tell it which embedding model / service to use, you give it a URL and an API key. It is going to take care of everything by itself. Nothing to do. No pipelines. No Llama index. No langchain. Nothing. A setting. Actually wrote a full-blown medium post just to say how cool this is. I have been using Elastic since version 0.2 and as far as FT generally... I kinda have 30 years of track record in choosing winners. Ask me about CPL from AOL one of these days.

Meilisearch, as it is, is great. However, if you have the chance, make it self-hosted. Meilisearch Cloud is just a bunch of incompetent people unable to solve any issues. Even when they solve something, the problem tends to occur again. Even if you pay for a better instance, it seems they keep the parameters as low as possible, causing multiple problems. If you don't want to end up with search freezes lasting for three hours frequently, don't go with Meilisearch Cloud.

I am using Meilisearch almost since the beginning and it has never let me down. Never had any serious problems with it. It is much better for our company than the overley complicated Elasticsearch we were using before.
