FAISS - Should vectors be pre-stored in a vector DB first?

[VirajVaitha123]

Hi,

I hope you're well.

let's say a user wants to search a document using semantic search, should I be downloading the embeddings/vector from a vectordb (or any cloud storage), embed the query, and then insert these into fais?

Or should I be using FAIS to encode and search at the same time?

Ideally my app allows users to search a single document, but also the option to search all their uploaded documents in one go. If I need to download the embeddings it's not to bad for a single document, but for all their documents could be time consuming.

Thanks,

Viraj
