I wonder when this issue with GPMC´s filter will be fixed, that search can be run only with EN keyboard layout? If there is other regional settings set in server and you are using GPMC, you won´t find any results when trying to search gpo settings using filters. This was a priceless tip for me few years ago, after this I didn´t need to run through all nodes in GPMC trying to find desired set manually. Just use the search with good keywords and you are done. I´m also amazed, that this "bug" isn´t discussed very wide anywhere. I´ve tought this trick to around 10 admins so far and they were very thankful.
Treat this thread as feedback to MS. And take advantage this feature. Cheers!
When typing the keywords here, make sure you are using EN keyboard layout.
