Assistant retrieval searching limited portion of document

I know this has been asked several times but I’ve never seen a sufficient answer.

Is there a way to get the assistant to search the full content of a file that is provided? The file in question is a < 100KB json file containing about 30-40 tasks from my ticketing software.

I would like the assistant to categorize tasks based on content, but I can’t even get it to search all tasks with a given text in them. It will bail out after finding like 5 samples.

Even if I add “use the whole file” or something similar to the instructions it will not work.

And to top it off, I keep hitting the rate limit extremely fast.

Is this even the right approach to solving this problem? should I look into embeddings? Would appreciate any help
