Using something like Weaviate, which can be started in Docker with a one-liner, will give the ability to move away or toward dense vectors by concept. While doing dot product with manual code is fairly easy, using Weaviate to do the lifting (for embeddings as well) makes things super simple.

that means you need docker running and the dependencies explode if you take this approach. I really like the tight dependency tree.
