EasyFind and Photoshop

Does anyone know what is the fastest way to search for metadata/file-info in Photoshop Documents?
When I use Scan All Files in the right window of EasyFind (the one you can open or close), it works, but it takes a real long time to get results.

Thanks a lot for your help!

EasyFind treats all files as plain text and therefore using EasyFind to scan binary data is usally not recommended (and very slow if the files are huge).
