FEAT: add collection api to retrieve record with filtered metadata

[edwinkys]

Purpose & use case

We should add an API for the Collection called maybe filter that takes in the condition and return a hash map of VectorID to Record. This filter API is useful for users who need to retrieve some of records which data match the provided condition.

Hi @edwinkys , is this issue open to contribution? If yes, is it possible to elaborate a bit on the ask here?
Thank you

Hey, thank you for being interested in contributing. This issue is currently suspended.

Essentially, we want to create a method of collection, Collection.filter(...) where calling this allows users to retrieve vector records based on filter on the metadata.

pub fn filter(...) -> Result<HashMap<VectorID, Record>, Error>

The problem is that due to the flexible nature of the Metadata, I'm still thinking of what is the best way to solve this problem. I'd love to hear your thoughts tho 😁

@edwinkys Thanks for the response, I am still playing around with the repo in general so I think you would have better expertise in the direction of how filtering should go, as I dig around the code I will keep this ticket in mind, for now I don't have any thoughts on this
thanks
