How do I search through associations with searchkick (elastic search) together aggregations

Hello folks,
I’m trying to do a search query through an association. Here’s what I have.
I have Property model which has_many :characteristics, as: characteristicable on one side. On the other side I have Characteristic model which belongs_to :characteristicable, polymorphic true .
I use Elastic Search in my rails app with the searchkick gem. What I’m trying to achieve is to search for characteristics in the Property model so that I can show all the properties that have that characteristic.
I’ve been playing around inside rails c and go something, but not quite what I’m looking for yet:

characteristic = Characteristic.find_by name: "Airconditioning"
# this finds the first instance with name "Airconditioning" in the Characteristics table
characteristic.characteristicable
# this gets the property that is linked to this instance of characteristic
characteristic = Characteristic.joins(:characteristicable).where name: "Airconditioning"
=> #<Characteristic::ActiveRecord_Relation:0x4d94>
#<Characteristic:0x00007fd694a789e8
  id: 20,
  name: "Airconditioning",

  characteristicable_type: "Property",
  characteristicable_id: 4,
  user_id: 1>,
[48] pry(main)> characteristic = Characteristic.joins(:characteristicable).where characteristicable_type: "Property"
=> #<Characteristic::ActiveRecord_Relation:0x4da8>
[49] pry(main)> characteristic
=> #<Characteristic::ActiveRecord_Relation:0x4da8>
[50] pry(main)> characteristic.find_by name: "Airconditioning"
ActiveRecord::EagerLoadPolymorphicError: Cannot eagerly load the polymorphic association :characteristicable
