Escaping

Slash in query cause "Failed to parse query" error.

Elasticsearch::API::Utils.__escape(q)

Model

Gestion automatique de la méthode as_indexed_json.

search_index([:label, :blocks => [:title, :content, :legend]])

Gestion par défaut du mapping : les attributs doivent être ajoutés à la méthode as_indexed_json.

search_index([:label, :blocks => [:title, :content, :legend]]) do
  indexes :published_start_at, :type => :date
  indexes :published_end_at, :type => :date
end

search_index([:content]) do
  indexes :user do
    indexes :firstname
  end
  indexes :product do
    indexes :label
  end
end

# surcharge de as_indexed_json_attributes n'est plus nécessaire
def as_indexed_json_attributes_with_more
  json = as_indexed_json_attributes_without_more
  json[:only] += [:published_start_at, :published_end_at]
  json
end
alias_method_chain :as_indexed_json_attributes, :more

Seeds

# create_index! et import
ActiveRecord::Base.init_indexes(Rails.env.development?)

Page.seed(:name) do |p|
  p.name = 'home'
  p.label = 'Accueil'
end

Controller

L'utilisation de DevagnosElasticsearch::Search.search est équivalente à celle de Elasticsearch::Model.search.

if params[:q].present?
  @search_results = DevagnosElasticsearch::Search.search(params[:q], [Page, DevagnosBlog::Article]).page(params[:page]).per_page(5).records
end

L'utilisation de DevagnosElasticsearch::Search.search_dsl permet d'utiliser Elasticsearch::DSL.

if params[:q].present?
  q = Elasticsearch::API::Utils.__escape(params[:q])
  search_results = DevagnosElasticsearch::Search.search_dsl([Page, LgdPage, DevagnosBlog::Article]) do
    search do
      query do
        bool do
          must do
            query_string do
              default_field '_all'
              query q
            end
          end
          # must do
          #   simple_query_string do
          #     query q
          #   end
          # end

          must do
            filtered do
              filter do
                _or do
                  missing field: 'published_start_at'
                  range :published_start_at do
                    lte 'now/d'
                  end
                end
                # _or do
                #   missing field: 'published'
                #   term published: true
                # end
                # _or do
                #   missing field: 'type'
                #   terms type: %w(content faq home resource)
                # end
              end
            end
          end

          must do
            filtered do
              filter do
                _or do
                  missing field: 'published_end_at'
                  range :published_end_at do
                    gte 'now/d'
                  end
                end
              end
            end
          end
        end
      end
    end
  end

  @search_results = search_results.page(params[:page]).per_page(5).records
  # result_ids = search_results.collect(&:id).collect(&:to_i)
end
