Short answer
Yes. In the Ask screen, use the Focus On menu to choose whether AskTuring searches your entire Index or only selected files and folders.
Full explanation
By default, AskTuring searches across your entire Index when answering a question. If you only want the AI to reference certain folders or files:
Go to the Ask screen.
Locate the Focus On menu in the lower-right corner above the chat box.
Select A Selection to choose specific files and folders to focus on.
Check the box next to the files you want to focus on. you can also check the box next to a folder and focus on all files in that folder.
Ask your question as usual — AskTuring will limit its responses to your chosen files.
Tip
This setting applies only to your current question or conversation — you can reset it anytime by switching back to All in the Focus On menu.
To ensure maximum accuracy when limiting the AI to specific sources, also enable Chat with Index Only so the response is based exclusively on your selected documents.
