Hey Very important to me Is it possible

what do you mean by a portion of the embeddings? Can you give an example?

very hacky, but if you know the node_id (I think you can get this from response.source_nodes), you could do something like

index._index_struct.embeddings_dict[<node_id>]

Ok I change my question. I can merge two simple vector indices? Or can I take a portion of the json of a built index? Eg I have 1 big index, with data from 2023 and 2022. Can i split them in two indices?

I don't think there is a way to split or merge them once they've been built 🤔 At least not easily. Maybe raise a github issue for this

Currently, the closest thing to merging is using composability and combining both vector indexes into a list index
