Ruby on rails - ElasticSearch & Tire.搜索具有嵌套属性的对象

Question

我花了好几个小时试图解决这个问题。我希望有人能帮助我。

首先，这里有一些代码来说明这个结构:

class Company < ActiveRecord::Base
  include Tire::Model::Search
  include Tire::Model::Callbacks
  attr_accessible :name, :website, :addresses_attributes
  has_many :addresses, dependent: :destroy
  accepts_nested_attributes_for :addresses, allow_destroy: true
  after_touch() { tire.update_index }
  include_root_in_json = false
  mapping do
    indexes :name, boost: 10
    indexes :addresses do
      indexes :street
    end
  end
  def self.search(params)
    s = tire.search(load: true) do
    query do
      boolean do
        must { string params[:query] } if params[:query]
        must { term "addresses.street", params[:location] } if params[:location]
      end
    end
    s.results
  end
  def to_indexed_json
    to_json( include: { addresses: { only: [:street] } } )
  end
end

class Address < ActiveRecord::Base
  # Attributes
  attr_accessible :street
  # Associations
  belongs_to :company, touch: true
end

当我试图搜索具有特定街道名称的公司(呼叫Company.search({location: 'example_street_name', query: 'example_name'}))时，我没有得到任何结果。

索引对我来说很好。这是其中一个请求:

curl -X POST "http://localhost:9200/companies/company/1351" -d '{
  "created_at": "2012-12-29T13:41:17Z",
  "name": "test name",
  "updated_at": "2012-12-29T13:41:17Z",
  "website": "text.website.com",
  "addresses": [
    {
      "street": "test street name"
    }
  ]
}'

我尝试了很多方法来得到结果。毫无效果。看来我一定错过了一些基本的东西。

您正在使用term查询"地址"。Street "字段，它不被分析，所以你必须传入小写的等值。

尝试使用match查询
