使用弹性搜索来过滤带有空格的标签 [英] using elasticsearch to filter through tags with whitespace

问题描述

我正在使用带有mongoid的轮胎（https://github.com/karmi/tire）。这是我的模型定义：

  class SomethingWithTag 
 include Mongoid :: Document 
 include Mongoid :: Timestamps 
 field：tags_array，type：Array 
 
 include Tire :: Model :: Search 
 include Tire :: Model :: Callbacks 
 mapping do 
 indexes ：tags_array，type：：array，index：：not_analyzed 
 end 
 end 
  

  SomethingWithTag.tire.search {filter：terms，：tags_array => [hello]} 
 SomethingWithTag.tire.search {filter：terms，：tags_array => [world]} 
 SomethingWithTag.tire.search {filter：terms，：tags_array => [你好，世界]} 
  

但是以下内容不返回任何结果： / p>

  SomethingWithTag.tire.search {filter：terms，，tags_array => [你好世界]} 
  

我该怎么做才能使它工作？

解决方案

问题解决于：

使用关键字分析器为 tags_array 属性：

  class SomethingWithTag 
＃... 
 mapping do 
索引：tags_array，analyzer：'keyword'
 end 
 end 
  

I am using tire (https://github.com/karmi/tire) with mongoid. Here is my model definition:

class SomethingWithTag
  include Mongoid::Document
  include Mongoid::Timestamps
  field :tags_array, type: Array

  include Tire::Model::Search
  include Tire::Model::Callbacks
  mapping do
      indexes :tags_array, type: :array, index: :not_analyzed
  end
end

Say I have a document {tags_array: ["hello world"]}. Then the following queries work fine:

SomethingWithTag.tire.search { filter :terms, :tags_array => ["hello"] }
SomethingWithTag.tire.search { filter :terms, :tags_array => ["world"] }
SomethingWithTag.tire.search { filter :terms, :tags_array => ["hello", "world"] }

But the following doesn't return any results:

SomethingWithTag.tire.search { filter :terms, :tags_array => ["hello world"] }

What should I do to make it work?

解决方案

Issue solved at :

Use the keyword analyzer for the tags_array property:

class SomethingWithTag
  # ...
  mapping do
    indexes :tags_array, analyzer: 'keyword'
  end
end
