relativity v0.1a

relativity is search engine for ruby_on_rails applications. It uses a NoSQL Key-Value store to create searchable records. It is a modified copy of the data stored in your main database (MySQL, etc). It is read-only (not for storage and editing).

Example

item.rb

class Item << ActiveRecord:Base
  relativity_search_records do
    string :name
  end
end

irb:

Item.create!({:name => "Test Item", :properties => {:height => "6 feet", :width => "24 inches"}})
Item.search_by_key(:height, "6 feet") # [ Item(1) ]
Item.search_by_key(:properties,  {:height => "6 feet", :width => "24 inches"}) # [ Item(1) ]

Requirements

ruby >= 1.9.2
rails >= 3.x
MongoDB

Installation

1) Put it in your Gemfile and run ‘bundle install`

OR `gem install relativity`

2) rails generate relativity:install

Usage

In your ActiveRecord model, set the search_keys method:

class Item < ActiveRecord:Base
  search_keys do
    string :name
  end
end

Then you can search via the class method ‘search_by_key`.

IMPORTANT NOTES

This is a search key-value store, and is in no way a datastore. It is purely for search records (it modifies some values for easier search.
