@mib2berlin If a bookmark doesn't have "sushi" or "japan" in its name or URL, it won't show up in your search results. And if you want to quickly look at all the bookmarks in the "japan" folder to find the one you're looking for, there's no way to do that. You have to step through the folders to get to the "japan" folder.
I'm sorry my previous expression didn't make quick sense to you, I'm not an English user and I've been using deepL to write this post.
