How work when have multilang model (Globalize)

[pyromaniac]

Yeah, I've got some Ideas. At first, you need to index your localized values. Assume you have User model with localized name:

class UsersIndex < Chewy::Index
  define_type User do
    # storing name translations as object
    field :name_translations, type: 'object'
    # you can even define custom properties for every translation (this goes first because of ES dynamic templates resolving rules)
    template 'name_translations.ru', type: 'string', index: 'analyzed', analyzer: 'custom_russian_analyzer'
    # in order to define every name translation properties, we are using dynamic templates
    template 'name_translations.*', type: 'string', index: 'analyzed', analyzer: 'custom_name_analyzer'

    # we are using `name_translations` field name instead of `name` to define type own methods
    # It will be useful if you will decide to use loaded and wrapped ES documents instead of loading AR objects.
    #   UsersIndex.query( .... ).first.name # will return name in current locale.
    def name
      name_translations[I18n.locale.to_s]
    end
  end
end

So, after indexing you have to query for data:

# you have to specify fields for current query according to current locale
UsersIndex.query(query_string: {fields: ["name_translations.#{I18n.locale}"], query: 'Jonny', default_operator: 'and', lenient: true})

That's it. I was recalling this from memory, so I'm not sure examples will work as is, you'll have to experiment.
I would appreciate if you will describe you adventure somewhere in wiki here. Would be a great first howto.

Thank you, it's work like a charm. My English is very poor. I am Quebecois. So I forker your example to make a multilang example. I give you permission to clone and put the documentation that you desire.

Free for you to do what you want it

By the way, your solution work A1. I add the existing_filter for the model do not have all traduction.

It will be better to use wildcard notation here, since this templates are similar: template 'title_translations.*', type: 'string', index: 'analyzed'

And thanks for example.
