Simple algorithm to return a relevancy score for a blob of text based upon the provided keyword.
This algorithm could then be applied to sorting search results similar to Google
Add this line to your application's Gemfile:
gem 'relevancy_score'And then execute:
$ bundle
Or install it yourself as:
$ gem install relevancy_score
Acquire hash with related data one may find from search results, and choose a keyword that may return this data:
{
title: "The Empire Strikes Back",

The Galactic Empire, under the leadership of the villainous Darth Vader and the Emperor, is in pursuit of Luke Skywalker and the rest of the Rebel Alliance. While Vader chases a small band of Luke's friends - Han Solo, Princess Leia Organa, and others - across the galaxy, Luke studies the Force under Jedi Master Yoda. When Vader captures Luke's friends, Luke must decide whether to complete his training and become a full Jedi Knight or to confront Vader and save them."
