如何设置轮胎弹性搜索的默认分析仪？ [英] How do I set the default analyzer for elastic search with tire?

问题描述

最近我一直在使用ruby在rails上进行弹性搜索。我无法获取我的数据索引，所以我可以搜索具有复数和非复数关键字的项目。

轮胎将允许我为每个映射属性分配一个分析器：

 映射do 
索引标题，分析器：'snowball'
索引体，分析器：'snowball '
 end 
  

现在，说我的标题为'tests' / p>

如果我使用查询中的属性进行搜索：
http：// localhost：9200 / myindex / mymapping / _search？q = title：test
它将工作。

但是，如果我没有指定如下属性进行常规搜索：

http：// localhost：9200 / myindex / mymapping / _search？q = test

它不会找到文档。

如何指定我想要默认分析器为雪球，所以我不必指定属性I想搜索？

p.s。我正在使用轮胎宝石。所以请尽可能最好地回答这个问题。

解决方案

可以使用索引设置更改默认分析器： p>

  require'rubygems'
 require'tire'
 
轮胎.index'articles'do 
 delete 
 create：settings => {
：index => {
：analysis => {
：analyzer => {
：default => {
：type => 'snowball'
} 
} 
} 
} 
}，
：mappings => {
：article => {
：properties => {
：title => {：type => 'string'，：analyzer => 'snowball'}，
：body => {：type => 'string'，：analyzer => 'snowball'} 
} 
} 
} 
 
 store：title => 'Tests'，：body => 多元
 store：title => 'Test'，：body => 单数
 
刷新
结束
  

I have been experimenting with elasticsearch lately with ruby on rails. I am having trouble getting my data indexed so I can search for items with both plural, and non-plural keywords.

Tire will allow me to assign an analyzer per mapping attribute:

mapping do
  indexes title, analyzer: 'snowball'
  indexes body, analyzer: 'snowball'
end

Now, say I have a keyword in the title of 'tests'

if I do a search with the attribute in the query: http://localhost:9200/myindex/mymapping/_search?q=title:test It will work.

However, if I do a general search without specifying the attribute like so:
http://localhost:9200/myindex/mymapping/_search?q=test

It will not find the document.

How do I specify that I want the default analyzer to be 'snowball' so I don't have to specify the attribute I want to search on?

p.s. I am using the Tire Gem. So please answer as best as you can taking that into account.

解决方案

It's possible to change default analyzer using index settings:

require 'rubygems'
require 'tire'

Tire.index 'articles' do
  delete
  create :settings => {
      :index => {
        :analysis => {
          :analyzer => {
            :default => {
              :type => 'snowball'
            }
          }
        }
      }
    },
    :mappings => {
      :article => {
        :properties => {
          :title    => { :type => 'string', :analyzer => 'snowball'},
          :body     => { :type => 'string', :analyzer => 'snowball'}
        }
      }
    }

  store :title => 'Tests', :body => "Plural"
  store :title => 'Test', :body => "Singular"

  refresh
end
