[Feature Request] Use WAND Top-K Retrieval about retriv HOT 3 CLOSED

Hi, I have a working WAND implementation, but it is slower than brute force vector operations.
I am now considering more advanced WAND-based approaches. I hope to add one soon.

Hi, thanks for the suggestion and code!

I have an implementation of another optimization algorithm for top-k retrieval on my local branch. Unfortunately, it slows down the retrieval because (I suspect) it requires more instructions to be executed (even if they are applied to less data).
Current implementation heavily relies on vector computations, which are fairly optimized on modern CPUs.

I will let you know if WAND improves efficiency over the current implementation.

Unfortunately, I don't think this will happen anytime soon. The lexical retriever is already reasonably efficient, and there are other things I prefer to prioritize.

I will close for now.
