Also is there a small to big indexing /

the one with paragraph as a parent and sentences as the children

instead of an arbitrary window size

is it this one ?

hmm I don't think we nescarily have something built in to to that. But you could certainly build that with existing tools. That's just a recursive retriever

I think the hard part with that is you need some step to identify paragraphs in the first place

(using unstructured?)

Something like this maybe, but instead of varying chunk sizes, you split into paragraphs and sentences? https://docs.llamaindex.ai/en/stable/examples/retrievers/recursive_retriever_nodes.html

thank you @Logan M

gonna look into it
