Rails 4 + Serialization: Disable ActiveModel::Serializer for view

I have an API with a search function that returns a list of client objects. Normally I like to use my client serializer to control which attributes are returned. However, when searching, I'd like to require fewer attributes so that the search can be completed more quickly.

My controller

def index
  @clients = Client.order("created_at ASC")

    if params[:search].present?
      @clients = Client.select('name', 'id').where("(name like ?) OR (name like ?)", "%#{params[:search]}%", "%#{params[:search].titleize}%")
    end

    paginate json: @clients, serializer: nil, per_page: 25
end

serializer: nil has no effect because my logs show each returned client grabbing all it's associations that I don't need and still shows active_model_serializers throughout the log.

log

Client Load (0.8ms)  SELECT  "clients"."name", "clients"."id" FROM "clients" WHERE ((name like '%ta%') OR (name like '%Ta%')) LIMIT 25 OFFSET 0
# I don't need any of this (below)
[active_model_serializers]   CheckIn Load (1.3ms)  SELECT "check_ins".* FROM "check_ins" WHERE "check_ins"."client_id" = $1  ORDER BY created_at ASC  [["client_id", 1363]]
[active_model_serializers]   Payment Load (0.1ms)  SELECT "payments".* FROM "payments" WHERE "payments"."client_id" = $1  [["client_id", 1363]]
[active_model_serializers]   Purchase Load (0.1ms)  SELECT "purchases".* FROM "purchases" WHERE "purchases"."client_id" = $1  [["client_id", 1363]]
[active_model_serializers]   Program Load (0.2ms)  SELECT "programs".* FROM "programs" WHERE "programs"."client_id" = $1  [["client_id", 1363]]

What can I do to prevent the additional attributes from being loaded?

I was able to solve my problem by changing the following line:

paginate json: @clients, serializer: nil, per_page: 25

to:

paginate json: @clients, adapter: false, per_page: 25
