Hi Jan,

Yes this is a new feature where you can search a similar group based on advanced search when you viewing group details as you can see from my screenshot here, http://screencast.com/t/S7Yc6IWJHtn . When you click on the group title from my screenshot earlier, you will be redirected to group matches page, http://screencast.com/t/mPTnVtgNmLcu .

Hope these help.
