I'm biased, but I'd recommend exploring Typesense for search.

It's an open source alternative to Algolia + Pinecone, optimized for speed (since it's in-memory) and an out-of-the-box dev experience. E-commerce is also a very common use-case I see among our users.

Here's a live demo with 32M songs: https://songs-search.typesense.org/

Disclaimer: I work on Typesense.

I can also highly recommend TypeSense and have no affiliation. You'll save a lot of money and get much faster results.
