If you wanted to search groups in buddypress you can simply navigate to (http://sitename/groups/?s=searchstring) But is it possible to pass other parameters to url like orderby=membernumbers&order=ASC or tags= or search exact phrase ... . So I'm wondering if any of these actions is possible?
1- Sort group search results based on number of members
2- Search groups Only by their Tags... .
3- Search grous based on tags with exact phrases only.
