Bridge - subfolder search does not work

Hello,

I want to search and sort a hard drive with really many images and subfolders with a smartscollection. Unfortunately, Bridge does not search the subfolders as set. Only if I have ever opened a folder in Bridge, the content will be displayed according to the criteria in the Smartsammlung.

Open all folders first so that they are considered in the bridge search is an absurdity and would last forever.

Have already been able to search the cache for the hard drive but no success. The checkmarks in the smartscollection "search all folders and subfolders" are set. I do not know how to continue.
