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

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.
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
