A search for R35E7, a functioning station in Wisconsin, USA, yields no results using either Firefox or Chrome/Chromium.
I imagine that users will expect that searches of stations, even ones which have not yet been claimed through ShakeNet, will yield some sort of result.
I should amend this to say that a search for other functioning stations yields nothing either.
The search functionality is limited to searching members. While you can search by station name, if there is no member tied to it, it won’t work. You are filtering members by station, there is no station search ( yet ).
