@Psancs05 thx

Great catch - updated 🙏

@virattt Do you know the difference between using:
query_embedding = model(**query_encoding).last_hidden_state.squeeze(0)
query_embedding = model(**query_encoding).last_hidden_state.mean(dim=1)

I have tested both and seems that the squeeze(0) returns better quality similar documents (maybe it's just the use-case I tried)

query_embedding = model(**query_encoding).last_hidden_state.squeeze(0) is correct since it returns a vector per token, whilst
query_embedding = model(**query_encoding).last_hidden_state.mean(dim=1) returns a single vector averaged over all tokens.
