Rails Elasticsearch with conditions

I use Elasticsearch in my Rails application (elasticsearch-model, elasticsearch-rails gems). I wrote a simple search:

def search
    @posts = params[:term] ? Post.search(params[:term]) : [] 
    render json: @posts
end

It works good. But I made some fixes in order to do search among 'deleted=false' and 'enabled=true' subset then :

def search
    @posts = params[:term] ? Post.existing.enabled.search(params[:term]) : [] 
    render json: @posts
end

Post

class Post < ActiveRecord::Base
  include Elasticsearch::Model
  include Elasticsearch::Model::Callbacks

    scope :existing, ->{ where(deleted: false) }
    scope :enabled,  ->{ where(enabled: true) }
end
Post.import

It doesn't work - I see the same results as in the previous case(with any value in 'deleted' and 'existing' columns. How can I fix it? Thanks in advance.

def self.search query, options = {}
  search_definition = {
    query: {},
    filter: {}
  }
  __add_filter = lambda do |f|
    search_definition[:filter][:and] ||= []
    search_definition[:filter][:and] |= [f]
  end
  if options[:existing]
    __add_filter.({ term: {'deleted' => false}})
  end
  if options[:enabled]
    __add_filter.({ term: {'enabled' => true}})
  end
  unless query.blank?
    search_definition[:query] = {
      # add your query logic
    }
  else
    search_definition[:query] = { match_all: {}}
  end
  __elasticsearch__.search(search_definition)
end

Change how your search method works.

@posts = params[:term] ? Post.search(params[:term], existing: true, enabled: true) : []

Post model

def self.search query, options = {}
  __add_filter = lambda do |f|
    search_definition[:filter][:and] ||= []
    search_definition[:filter][:and] |= [f]
  end
  search_definition = {
    query: {},
    filter: {}
  }
  if options[:existing]
    __add_filter.({ term: {'deleted' => false}})
  end
  if options[:enabled]
    __add_filter.({ term: {'enabled' => true}})
  end
  unless query.blank?
    search_definition[:query] = {
      # add your query logic
    }
  else
    search_definition[:query] = { match_all: {}}
  end
  __elasticsearch__.search(search_definition)
end
