How can I limit Search Field to a toolbar's items?

Is it possible for a Search Field to be limited to a particular toolbar instead of Favorites?
Alternatively, how can I type a few characters and highlight any matching menu items?
Dopus-Menu-Button-With-Search

The Search field search below the current folder. It does not search toolbar content. (You were presumably in the Favorites folder when you made the screenshot.)

Yes, I was in Favorites.

Perhaps a toolbar search feature could be added to the wish list?

In the mean time, I set up a couple of the top-level menu button(s), that show the folder that holds the shortcuts / exe files, when I click the button. I can then use the search bar to search inside that folder.

Thanks!
