It does not appear that there’s a means for searching for one’s own draft notebooks within ‘My Notebooks’. The search tool will bring up other public notebooks, but won’t return matches within my drafts. I would find it helpful to add, and so thought that I’d raise it here for consideration.
Thank you! This now appears to be enabled.
Yes! We’ve pushed out an update that allows you to search private (and shared) notebooks … and also improves search results across the board.
