Rails/Tire -防止属性被索引

Question

我正在尝试使用Rails (3.2.8)、Tire和ElasticSearch创建一个自定义映射。

我希望“标题”和“描述”是唯一可搜索/索引的属性.但是，我似乎无法做到这一点：

以下是我的模型：

class BlogPost < ActiveRecord::Base
  attr_accessible :title, :description, :attachment, :attachment_thumbnail

  include Tire::Model::Search
  include Tire::Model::Callbacks

  tire.mapping do
    indexes :id, :type => 'integer', :index => :not_analyzed, :include_in_all => false
    indexes :attachment, :type => 'string', :index => :not_analyzed, :include_in_all => false
    indexes :attachment_thumbnail, :type => 'string', :index => :not_analyzed, :include_in_all => false
    indexes :title, analyzer: 'snowball', boost: 100
    indexes :description, analyzer: 'snowball', boost: 100
  end

  def self.search(params)
    tire.search(load: true, page: params[:page], per_page: 15) do
      query do
        boolean do
          must { string params[:query], default_operator: "AND" } if params[:query].present?
        end
      end
    end
  end

end

Answer 1

您需要将index设置为no

indexes :id, :type => 'integer', :index => :no, :include_in_all => false
indexes :attachment, :type => 'string', :index => :no, :include_in_all => false
indexes :attachment_thumbnail, :type => 'string', :index => :no, :include_in_all => false
indexes :title, analyzer: 'snowball', boost: 100
indexes :description, analyzer: 'snowball', boost: 100

使用not_analysed只会防止字段被分解为令牌--它仍将包含在索引中。

如果更改映射，则应重新编制整个数据的索引。如果是测试数据，则为，则删除索引。创建索引并再次对数据进行索引。我猜您在索引数据后尝试添加:include_in_all => false。
