nonstop backup restore :where is a search function?

Hello,
I just make the first steps with the new version 2015.
Nonstop Backup now runs and backup.
Restore is possible if I know date and path.
But I miss a search option if I only knew the filename.
I am sure previous versions had a search option. Release infos shows a big list of options cutted out but I wasn't able to find that this feature is also ereased.

Please help me with a description how to do a filesearch in nonstop backup.
