I have a workaround, but it's annoying for me because I normally search within a notebook, but if you go right to the top under "HOME", there's "NOTES". Click on Notes to highlight it and then search. It will do the search and work, but it will pull up EVERYTHING with your search parameters instead of just what's in your specific notebook that you want to search in. Annoying, but it's a workaround until this is fixed.
