轮胎术语过滤器不工作 [英] tire terms filter not working

问题描述

我正在尝试用轮胎/弹性搜索来实现像范围功能。为什么这不工作，即使我有状态为Test1或Test2的条目？结果总是为空。

  collection = @ model.search（：page => page，：per_page => per_page ）do | s | 
 s.query {all} 
 s.filter：terms，：status => [Test1，Test2] 
 s.sort {by：＃{column}，＃{direction}} 
 end 
  / pre> 
 
 
该方法工作正常，没有过滤器。过滤方法有问题吗？我检查了轮胎doku ....它应该工作。
 
 
 
谢谢！ ：）
解决方案
您的问题最可能是由于使用状态的默认映射字段，它将标记它 - 小写，分为单词等。
 
 
 
比较这两个：
  http：// localhost：9200 / myindex / _analyze？text = Text1& analyzer = standard 
 
 http：// localhost：9200 / myindex / _analyze？text = Text1& analyzer = keyword 
  
您的案例中的解决方案是使用<$在您的映射中，c $ c>关键字分析器（或将字段设置为 not_analyzed ）。当该字段不是枚举类型的数据时，您可以使用多字段功能。
 
 
 
一个工作的Ruby版本将如下所示：
  require'tire'
 
 Tire.index（'myindex'）do 
 delete 
创建映射：{
文档：{
属性：{
 status：{type：'string'，analyzer：'keyword'} 
} 
} 
} 
 
存储状态：'Test1' 
商店状态：'Test2'
 
刷新
结束
 
 search = Tire.search'myindex'做
查询$ $ $ $ b过滤do 
查询{all} 
过滤器：条件，状态：['Test1'] 
 end 
 end 
 end 
 
 puts search.results.to_a.inspect 
  
 
 
 
 
 
 
注意：很少有可能 - 这个案例是一个例外 - 提供合理的建议没有提供索引映射，示例数据等。
 
I'm trying to achieve a "scope-like" function with tire/elasticsearch. Why is this not working, even when i have entries with status "Test1" or "Test2"? The results are always empty.
  collection = @model.search(:page => page, :per_page => per_page) do |s|
    s.query {all}
    s.filter :terms, :status => ["Test1", "Test2"]
    s.sort {by :"#{column}", "#{direction}"}
  end 
The method works fine without the filter. Is something wrong with the filter method?! I've checked the tire doku....it should work.

Thanks! :)
解决方案
Your issue is most probably being caused by using the default mappings for the status field, which would tokenize it -- downcase, split into words, etc.

Compare these two:
http://localhost:9200/myindex/_analyze?text=Text1&analyzer=standard

http://localhost:9200/myindex/_analyze?text=Text1&analyzer=keyword
The solution in your case is to use the keyword analyzer (or set the field to not_analyzed) in your mapping. When the field would not be an "enum" type of data, you could use the multi-field feature.

A working Ruby version would look like this:
require 'tire'

Tire.index('myindex') do
  delete
  create mappings: {
    document: {
      properties: {
        status: { type: 'string', analyzer: 'keyword' }
      }
    }
  }

  store status: 'Test1'
  store status: 'Test2'

  refresh
end

search = Tire.search 'myindex' do
  query do
    filtered do
      query { all }
      filter :terms, status: ['Test1']
    end
  end
end

puts search.results.to_a.inspect




Note: It's rarely possible -- this case being an exception -- to offer reasonable advice when no index mappings, example data, etc. are provided.
