RSpec: invalid model with searchkick

I'm not very sure I'm doing it right, but I have two models: House that has_one Address.

The Address model has:

class Address < ApplicationRecord
  searchkick
  belongs_to :house
end

I'm trying to test my house_controller with RSpec like this

RSpec.describe HousesController do
 context 'GET #index' do
 before { get :index }
 it     { is_expected.to render_template('index') }

 it 'assigns @houses' do
  h = create(:house)
  expect(assigns(:houses).results).to eq([h])
end
...

Nevertheless I always get a result which is not the one I expect. The code of my controller is the following:

def index
 if params[:term].present?
  @houses = House.search(params[:term])
 else
  @houses = House.search('*')
 end
end

I'm not sure I understand it, but could it be that since I'm using FactoryBot, it is creating lots of houses, and then when getting in the index method, there's a bunch of houses there and not only and precisely h?

This is my failure:

Failures:

  1) HousesController GET #index assigns @houses

I'm starting with RSpec now and it's really taking me effort and hours to try to grab the grasp of it, thanks a lot in advance!
