Azure AI for Organization data. How to refer to the file names in prompts to get response

Hi

I went through Azure AI documentation to come up with ChatGPT like feature using Azure AI services for my data set.

I have created Azure Storage account and container to store my files. Created the deployment with GPT3.5 turbo model. Linked the container as source.

I could able to get the response for the prompts.

However, I would like to be more precise to get the answers from a given file uploaded, instead of referring to all the files.

I tried prompts like--

'Refer to "abc.txt", and generate the summary',

'Consider file with name "abc.txt", get me the entities from this file'. 

Unfortunately, I dont get the relevant response. I see model is not able to identify my reference file in the prompt.

Can you tell me how to ask or refer a file to get responses from that file in the prompt.

Do I need to use fields in indexe. I used fields "title" and "filepath" that gets generated automatically. Still no luck.

Can you help me here please.
