How do I filter records through other models

Owen asked in Rails

Desired result:

I want 2 things:

In my list of aggregation links I want to be able to add the aggregation of property characteristics (e.g., properties with a balcony), property type (e.g., villa, apartment, studio etc) and property condition (e.g., new, newly renovated, in construction etc.).
In my search form I want to have a select box / radio buttons for characteristics, property type and condition which (1) shows a collection of available items in the database and (2) when I select an item and it searches for all the properties with that characteristic / property type / condition.
Actual result:

When select a property type (like Villa) what I get are all the properties regardless of property type. The same for condition and characteristics.

With aggregation feature of the searchkick gem I'm also not able to show the aggregation of property type, condition or characteristics.

Within the documentation of searchkick they talk about it being able to search thru multiple models, but when I try that out in my controller what I get is the error:

Configuration

I have a rails app (v6.1.0) which has a Property (belongs to property_type, condition and has many characteristics thru characteristic_properties), PropertyType (has_many properties), Condition (has_many properties) and Characteristic (has_many properties thru characteristic_properties) model and I've implemented elastic search thru the searchkick gem.

Since then I've added with the help of seachkick aggregations of property attributes and I've added a Google map which shows where the properties are located on the map. And finally, I've added pagination with the Pagy gem. Taking this in consideration this is how #index looks in the properties_controller.rb

And this is how property.rb looks like

has_many :viewings, dependent: :destroy
has_many :users, through: :viewings
belongs_to :user

def address
[street, city, zip_code].compact.join(", ")
end

def address_changed?
street_changed? || city_changed? || zip_code_changed?
end

def search_data
attributes.merge location: { lat: latitude, lon: longitude }
end
end
This is my search form on the property results page:
