Edits without notes are a common mark of either beginners not quite sure of what they are doing (common risk of human error) or expert editors a bit too sure of what they are doing (also a common risk of human error). Despite that, we do not currently have any way to search for them specifically.

This seems like it would be (especially) a good thing to combine with a search for edits by beginner editors, so that people who are not adding any notes when not required can be suggested to do so more often.

To resolve this, we can add a "do not exist (edit has no notes)" option under "Edit Note Authors" in the edit search UI. We can also add some new voting suggestions (on the /vote landing page) for beginner edits without notes, and another for destructive edits without notes.
