User-defined filters - as seen in Vald #97

zygm0nt commented 3 years ago

I've looked into Vald and that's how I reached NGT. One of the features I look for is filtering of a given vector set. Vald boasts it can do it (https://vald.vdaas.org/docs/usecase/usage-example/ - 'Advanced use cases' section). Is it possible to do that filtering with bare NGT?

Hi. I am not so sure what the user-defined filters are, however, NGT does not have any filters.

Ok, I see. I'll try to go through vald sources to see how this is implemented on top of NGT.
