How to use data backed by API instead of ActiveRecord?

I would like to be able to use data with searchkick that is not via ActiveRecord / Mongoid. In my specific use case, I would like to sync data that is mapped to an API instead of a database.

For this specific use case, using an ActiveRecord supported db does not work because I have business logic that is encapsulated at the API layer for another service that is not written to the db but calculated at request time. So I'm currently in a place where we need to duplicate business logic in the searchkick layer or precompute all business logic and save it to the db.

So the best solution I see currently is to implement the ActiveRecord interface and have it fetch from my API but I was wondering if anyone had a better idea since that interface is relatively large.

Yes you can use some of Searchkick's classes to index and query non-DB data. For example these methods in your class or module allow you to create an index with bulk data and search it:

  def self.index_name
    "my_index_name"
  end

  def self.search(term, ...)
    query = Searchkick::Query.new(nil, term, ...)
    query.options[:index_name] = index_name
    query.execute
  end

  def self.reindex
    index = Searchkick::Index.new(index_name)
    if index.exists?
      index.delete
    end
    index.create(Searchkick::IndexOptions.new(index).index_options)
    Searchkick.client.bulk(
      index: index_name,
      body: generate_documents,
      refresh: true,
    )
  end

  def self.generate_documents
    documents = [
        {
          create: {
            data: {
              field_1: 1,
              field_2: "Something worth searching for in here",
            }
          }
        }
      ]
    documents
  end

With your queries you must remember to pass the load: false option. For example:

MyClass.search(
  "something in there?",
  load: false,
  fields: [:field_2],
  where: {field_1: 1},
  limit: 1,
  misspellings: {edit_distance: 2},
)

For your use case it sounds like you will need to add documents to an existing index from time to time. I don't think the Searchkick::Index class has anything to offer here and so you will need to write a method that descends to the client level and do whatever you want to do there:
