Has anyone experienced an issue with

Can you clarify what you mean? Or give some code sample?

for an example , a job contract , the salary is mentioned in page 9

when i ask a question about it to the llm, on terminal output i only see it retrived nodes of page 1

and when i ask it how many pages you have access to in a given pdf , it also says 1

while its a 9 page pdf

Well, its only retrievieing the topk, so its only every going to retrieve the top k nodes. Asking how many pages there are will never work

Sounds like you might just need to increase your top k,

index.as_query_engine(similarity_top_k=4) for example
