Creating index is very intensive

[konstantintuev]

I noticed that when creating an index, the passages are encoded twice:

• once, when creating the indexing plan
• one more time when doing the actual indexing

Is it possible to save the already encoded vectors, as encoding depending on hardware can take a very long time, especially if done twice for each passage per index creation/addition operation?
Also is it possible to reuse already created BERT embeddings when adding to index?
