Using Ruby's ElasticSearch gem that uses Kaminari for pagination and the Ruby GraphQL gem, this is a custom connection to bypass additional pagination. This assumes that you've already queried the correct paginated records from ElasticSearch and you're returning an `Elasticsearch::Model::Response` object.

elastic_search_connection.rb

class ElasticSearchConnection < GraphQL::Relay::BaseConnection
  def has_next_page
    !nodes.last_page?
  end

  def has_previous_page
    !nodes.first_page?
  end

  def cursor_from_node(node)
    if nodes.current_page == 1
      starting_offset = 0
    else
      starting_offset = nodes.limit_value * (nodes.current_page - 1)
    end

    idx = starting_offset + (sliced_nodes.find_index(node) + 1)
    Base64.strict_encode64(idx.to_s)
  end

  def start_cursor
    cursor_from_node(nodes.to_a.first)
  end

  def end_cursor
    cursor_from_node(nodes.to_a.last)
  end

  def paged_nodes
    sliced_nodes

  def sliced_nodes
    nodes.records
