Find notes with no text?

General
1

I have a tagged list of product reviews I’ve written. Whenever I receive a product, I create an empty note with a heading and the review tag. I’d like to find all products I haven’t reviewed, but would prefer not to add a reviewed tag. Is there a Search expression that will show notes with headings but without text?

Don’t know one but you can try it with -a.

It excludes all notes with an a, which is probably the most used letter.

Thanks for the idea. I use -the and that seems to do the job.

Thanks, again.
