If you want literal ‘word counts’ there are great tools for that (convert the PDF to text and use simply python). If you look up the ‘strawberry problem’ you will understand the challenge with your ask in the example. It could only come up with the literal answer correctly probably by letting it do code execution and do as I described above)
Now if this was an actual report text and you would ask it to create a list of the companies covered and which ones are mentioned the most you’d probably get a pretty good results. But again - if you judge the answer by the literal mention of the company name, you’d be better of with coding.
Lastly, your results will differ greatly based on the model you’re using.
Maybe you want to share a real document that you are working on and we see about that?
