Potential bug? Postprocessor error when vector search yields 0 results
Exception: IndexError: list index out of range
I think there's a decent chance this is a bug. I'm fairly certain this happens because I just moved to a new Vector Database that has no data in it, but the index itself has been created.
My code was working fine and my tests were passing, but when I cleared my DB this error occurred. I believe its happening because the vector search yields no results and then the postprocessor (SentenceTransformerRerank) has nothing to rerank. I would guess that even when the results are zero, the reranker shouldn't run or just returns nothing.
I've attached my code and full stack-trace in the thread.
Let me know if I need to move this somewhere else. Happy to do so, but given my lack of experience I thought there was a chance I was using the class wrong so I didn't want to post right away as a bug
