def index_resources
      Administrate::Search.new(index_scoped_resource, dashboard, search_term).run
 end

as seen here https://github.com/thoughtbot/administrate/compare/v0.16.0...v0.17.0?diff=unified

Woops, just hit this. Luckily the workaround is fairly easy for now. Just need to add

module Admin
  class ApplicationController < Administrate::ApplicationController

    def index_resources
      Administrate::Search.new(index_scoped_resource, dashboard, search_term).run
    end

  end
end
