Method: Tire::Model::Indexing::ClassMethods#mapping

Defined in:

lib/tire/model/indexing.rb

#mapping(*args) ⇒ Object

Define the mapping for the corresponding index, telling Elasticsearch how to understand your documents: what type is which property, whether it is analyzed or no, which analyzer to use, etc.

You may pass the top level mapping properties (such as _source or _all) as a Hash.

Usage:

class Article
  # ...
  mapping :_source => { :compress => true } do
    indexes :id,    :index    => :not_analyzed
    indexes :title, :analyzer => 'snowball', :boost => 100
    indexes :words, :as       => 'content.split(/\W/).length'

    indexes :comments do
      indexes :body
      indexes :author do
        indexes :name
      end
    end

    # ...
  end
end
