Yes! the problem is it's always searching the subfolders first. When there's ton of files in subfolders. It takes forever to finish the searching process. And fuzzy mode makes the searching even longer.

Searching the current folder will be very helpful, Thank you so much 

As you see the subfolder's results always shows first and it takes more than a minute to search all subfolders. But my target file is in current folder, and it won't appear before subfolders searching ended. 

If there's a way to only search the current folder or only show the current folder's searching result  will be very efficient in my case

When searching the subfolders, the file I wanted doesn't appear immediately, It takes a lot of time to search the subfolders. And those files in subfolders also match the fuzzy search makes the results a mess.
