Super simple full text search for any model if you're running against Postgresql for the database.

* High speed searching on any Rails model class simply by adding acts_as_tsearch to your model.
* Index is updated whenever you create or save a row in your model. Index updates are very fast. This happens behind the scenes using the typical Rails "magic".
* TSearch generates headlines which are short summaries showing where your search terms were found in the text. It even puts bold tags around the results.
* Easily scalable since it's all in your database. No sharing of file stores needed or redundant indexes repositories.

Example:

class Blog < ActiveRecord::Base
acts_as_tsearch :fields => ["title","description"]
end

Blog.find_by_tsearch("bob")
