Mongoid Search

Mongoid Search is a simple full text search implementation for Mongoid ORM.

Installation

In your Gemfile:

gem 'mongoid_search'

Then:

bundle install

Examples

class Product
  include Mongoid::Document
  include Mongoid::Search
  field :brand
  field :name

  references_many :tags
  refereced_in    :category

  search_in :brand, :name, :tags => :name, :category => :name
end

class Tag
  include Mongoid::Document
  field :name

  referenced_in :product
end

class Category
  include Mongoid::Document
  field :name

  references_many :products
end

Now when you save a product, you get a _keywords field automatically:

p = Product.new :brand => "Apple", :name => "iPhone"
p.tags << Tag.new(:name => "Amazing")
p.tags << Tag.new(:name => "Awesome")
p.tags << Tag.new(:name => "Superb")
p.save
=> true
p._keywords

Now you can run search, which will look in the _keywords field and return all matching results:

Product.search("apple iphone").size
=> 1

Note that the search is case insensitive, and accept partial searching too:

Product.search("ipho").size
=> 1

Options

match:
:any - match any occurrence
:all - match all ocurrences
Default is :any.

search_in :brand, :name, { :tags => :name }, { :match => :any }

Product.search("apple motorola").size
=> 1

search_in :brand, :name, { :tags => :name }, { :match => :all }

Product.search("apple motorola").size
=> 0

allow_empty_search:
true - match any occurrence
false - match all ocurrences
Default is false.

search_in :brand, :name, { :tags => :name }, { :allow_empty_search => true }

Product.search("").size
=> 1
