You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: job_posting_search.rb
    path of file: ./repos/code_fund_ads/app/models
    
    the code of the file until where you have to start completion: class JobPostingSearch < ApplicationSearchRecord
  FIELDS = %w[
    company_name
    country_codes
    description
    full_text_search
    job_types
    keywords
    organization_id
    p
    
  def initialize(attrs = {})
    super FIELDS, attrs
    self.full_text_search = full_text_search.to_s.downcase.split(" ").uniq.join(" ")
    (self.country_codes ||= []).reject!(&:blank?)
    (self.job_types ||= []).reject!(&:blank?)
    (self.keywords ||= []).reject!(&:blank?)
    (self.province_codes ||= []).reject!(&:blank?)
  end
