ActsAsTsearch
=============
Acts_as_tsearch is a plugin for Ruby on Rails which makes it simple to implement scalable, full text search for Rails if you're using PostgreSQL as your database. It wraps the built-in full text search engine of PostgreSQL with a familiar 'acts_as' implementation.
Home page: http://code.google.com/p/acts-as-tsearch/
Quick Start
-----------
* Preparing your PostgreSQL database
Add a text search configuration 'default':
CREATE TEXT SEARCH CONFIGURATION public.default ( COPY = pg_catalog.english )
For Postgres 8.2 and older follow http://code.google.com/p/acts-as-tsearch/wiki/PreparingYourPostgreSQLDatabase
* Adding the plugin:
ruby script/plugin install git://github.com/pka/acts_as_tsearch.git
* Add acts_as_tsearch to a model
class BlogEntry < ActiveRecord::Base
acts_as_tsearch :fields => ["title","description"]
end
* Do a search
blog_entries = BlogEntry.find_by_tsearch("bob")
puts blog_entries.tsearch_rank
puts blog_entries.size
puts blog_entries[0].title
...etc...
or using scopes:
blog_entry = BlogEntry.scoped_by_tsearch("bob").find(:first)
