如何使用 Retire 查询嵌套索引

Question

我有一个 Article 模型：

class Article < ActiveRecord::Base
  include Tire::Model::Search
  include Tire::Model::Callbacks

  settings default_options do
    mapping do
      indexes :id, index: :not_analyzed
      indexes :roles do
        indexes :machine_name, analyzer: 'keyword'
      end
      indexes :published_at, type: 'date', include_in_all: false
    end
  end
end

其中 default_options 是：

index: { store: { type: Rails.env.test? ? :memory : :niofs },
         analysis: {
           analyzer: {
             default: {
               tokenizer: "standard",
               filter: ["asciifolding", "lowercase", "snowball"],
               char_filter: ["html_strip"]
             }
           }
        }

我只是想在过滤角色的同时搜索文章，但我不知道该怎么做。我一直在尝试类似的事情但没有成功：

Tire.search("article") do
  query { string 'foo bar baz' }
  filter :nested, { path:'roles',
                    query: {
                      filtered: {
                        query: {
                          match_all: {}
                        },
                        filter: {
                          term:{'roles.machine_name' => ['da']}
                        }
                      }
                    }
                  }
end

这给我错误：

QueryParsingException[[development-oaciq::application-article] [nested] nested object under path [roles] is not of nested type];

Answer 1

找到这个 question 后，似乎不需要 nested 过滤器，可以这样做：

Tire.search("article") do
  query do
    string 'foo bar baz'
    term 'roles.machine_name', 'test'
  end
end
