Hi, I have a question about index separation for multiple users. Right now, my project has two main functions: One function selects and loads the index, the other is the chatting with the document part. Everything seems fine with one user, but when a second user logins and loads a file, both users that are logged in have the same file loaded, instead of two separate files for two separate users. My question is, are there any other ways of separation apart from multiprocessing in the flask example to separate the index loading for users?
