Any chance anyone has used the KeywordTableIndex successfully?

I am currently using it but getting an empty index returned every time.
Using the callback manager I can see that the payload to gpt 3.5 is successfully getting there and coming back with X keywords, but for some reason the index is always empty at the end...

Any ideas?
Using Service context with an AzureOpenAI deployment
Index is instantiated like this

Plain Text

index = KeywordTableIndex(nodes, max_keywords_per_chunk=3, use_async=False, service_context=service_context, show_progress=True)

index.summary returns 'None'

index.summary is not used for this

This works for me

Okay looks like I just missed that. The reason I was thinking the index was empty though is that I always get an empty response.

Just figured out though that my query was too dissimilar from the keywords so it wasn't returning anything I guess.

thanks for your help!
Really apprecaite all the work you put in

Yea keyword retrieval can be tricky! I usually would combine it with other methods to avoid having zero nodes returned

Speaking of, do you have any examples on hand for combining?

thats actually exactly what I would use 👍 I think this notebook does an ok-ish job at showing how it works
