Texticle exposes full text search capabilities from PostgreSQL, extending ActiveRecord with scopes making search easy and fun!

• Only works with PostgreSQL

• Rails 3

In the project’s Gemfile add

gem 'texticle', '~> 2.0', :require => 'texticle/rails'

• ActiveRecord outside of Rails 3

  require 'texticle'
  ActiveRecord::Base.extend(Texticle)
  

Your models now have access to the search method:

Game.search('Sonic') # will search through the model's :string columns
Game.search(:title => 'Mario')
Game.search_by_title('Street Fighter').search_by_system('PS3')
Game.search_by_title_and_system('Final Fantasy', 'PS2')
Game.search_by_title_or_system('Final Fantasy, 'PS3')

You can use ‘|’ and ‘&’ for logical conditions.

Game.search_by_title_or_system('Final Fantasy', 'PS3|Xbox')

To set proper searchig dictionary just override class method on your model:

def self.searchable_language
  'russian'
end

And all your queries would go right! And don`t forget to change the migration for indexes, like shown below.

You can have Postgresql use an index for the full-text search. To declare a full-text index, in a migration add code like the following:

execute "
    create index on email_logs using gin(to_tsvector('english', subject));
    create index on email_logs using gin(to_tsvector('english', email_address));"

In the above example, the table email_logs has two text columns that we search against, subject and email_address. You will need to add an index for every text/string column you query against, or else Postgresql will revert to a full table scan instead of using the indexes.

If you create these indexes, you should also switch to sql for your schema_format in ‘config/application.rb`:

config.active_record.schema_format = :sql

• Ruby 1.9.2

• gem install texticle
