How do I set the default analyzer for elastic search with tire?

Question

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-plur

Answer 1

It's easiest to set this in the elasticsearch.yml settings file:

index.number_of_shards: 2
index.number_of_replicas: 0
index.analysis.analyzer.default.type: snowball

Answer 2

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
