How to search for farm in Norwegian census

I can't find any drop down menu to search by farm name in the 1875 Norwegian census. I thought I used to be able to do that. I am searching for an Ole (born 1871) and brother Anton (born 1874) on the Gjerdet farm. I think, but have no evidence of this, that Gjerdet is a bruk of Grotaasen in Nordre Land. I tried searching for Ole and Anton, but only came up with the Ronning farm, which somehow didn't seem quite right - and the birthdates weren't quite right either. What am I doing wrong?
