This example uses Mongoid, Kaminari and Tire (ElasticSearch):
```ruby
require 'kaminari/models/mongoid_extension'
class Product
include Mongoid::Document
include Mongoid::Paranoia
include Mongoid::Timestamps
index :application_id, :unique => true
# NOTE Best to include after Mongoid
include Tire::Model::Search
include Tire::Model::Callbacks
include Kaminari::MongoidExtension::Criteria
include Kaminari::MongoidExtension::Document
end
```
Now you can paginate and search all you want:
```ruby
# Search and paginate
Product.tire.search :page => 1, :per_page => 100, :load => true do
query { string "Ho ho" }
#sort { by :rating, 'desc' }
end
# Paginate
Product.page(1).per(100)
```
Gotchas
-------
\* Use Model.tire.search/index, instead of Model.search which conflicts with Mongoid's index/search methods.
\* Use :load => true to return an array containing the model you're searching for instead of Tire::Result::Items.
\* Use :per\_page and :page with Model.tire.search, not the page/per methods.
\* Mongoid queries are not the same as ActiveRecord queries, see
\* MongoDB URL
\* Boolean queries are difficult
