I am encountering an issue with the file upload functionality. When I upload a single PDF file, it works perfectly. However, when I upload multiple PDF files (around seven), the end users are unable to retrieve information during their searches and receive a "not found" message.
Additionally, I would like to implement a feature where users can click on a reference, which would then direct them to the specific section of the text, highlighted in yellow.
Could you please provide guidance on how to resolve these issues?
