I have different notebooks and sometimes want to search in a specific one. I couldn't discover how to do the search without Googling for it.
It would be great if the rightclick menu for a notebook would have an option "Search notebook" that automatically copies notebook:"NotebookName " into the search bar when clicked.
I would expect that this feature is relatively fast to implement and useful for many users.
And no typing notebook:"NotebookName" is not feasible when NotebookName is very long or complex
At least add a search button to automatically add the notebook: search keyword for current notebook (would be better if it would be invisible in case it is too long)
