Фильтр поиска — только темы / только сообщения

Для меня это неведомый, странный и пугающий мир, но, судя по коду, контроллер находится здесь:

app/controllers/search_controller.rb

2c8dfc3db

# frozen_string_literal: true

class SearchController < ApplicationController
  before_action :cancel_overloaded_search, only: [:query]
  skip_before_action :check_xhr, only: :show
  after_action :add_noindex_header

  def self.valid_context_types
    %w[user topic category private_messages tag]
  end

  def show
    permitted_params = params.permit(:q, :page)
    @search_term = permitted_params[:q]

    # a q param has been given but it's not in the correct format
    # eg: ?q[foo]=bar
    raise Discourse::InvalidParameters.new(:q) if params[:q].present? && !@search_term.present?

    if @search_term.present? && @search_term.length < SiteSetting.min_search_term_length

This file has been truncated. show original

Фильтры поиска, похоже, находятся здесь:

          end
          
          def self.custom_topic_eager_load(tables = nil, &block)
            (@custom_topic_eager_loads ||= []) << (tables || block)
          end
          
          def self.custom_topic_eager_loads
            Array.wrap(@custom_topic_eager_loads)
          end
          
          advanced_filter(/\Ain:personal-direct\z/i) do |posts|
            if @guardian.user
              posts.joins("LEFT JOIN topic_allowed_groups tg ON posts.topic_id = tg.topic_id").where(
                <<~SQL,
                  tg.id IS NULL
                  AND posts.topic_id IN (
                    SELECT tau.topic_id
                    FROM topic_allowed_users tau
                    JOIN topic_allowed_users tau2
                    ON tau2.topic_id = tau.topic_id
                    AND tau2.id != tau.id
