The Headword search no longer works in the Bookstore tab. I know it used to, I've used it within the past couple of months.
I have noticed this too.
Bump
This appears to be working for me. Curious if you could try again and see if it's working as intended for you?
It's not working for me. Nothing I'm putting in is working. I'm putting in every word I can think of and I'm getting nothing.
EDIT: Can you show a screenshot of it working for you? I'd like to type in the same thing you did.
This is still not working for me.
Bumping because this is still an issue.
