You have to use the appropriate filter for the associated model. You can do this like:

ActiveAdmin.register User do
  filter :user_detail_name
end

Where name is an attribute of UserDetail model.

Update: Forgot to mention that ActiveAdmin utilizes ransack for search under the hood. Based on that you can use ransack 's syntax to setup your filters. Here are a couple of resources that could prove to be helpful:
