Mongoid Search is a simple full text search implementation for Mongoid ORM.
In your Gemfile:
gem 'mongoid_search'
Then:
bundle install
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
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
