===========

ActsAsLudiaはLudiaによるPostgreSQLの高速全文検索機能をRuby on Railsに付加
するプラグインです．

ActsAsLudiaはActiveRecordモジュールにfind_fulltextメソッドを追加します．

class Article < ActiveRecord::Base
  acts_as_ludia
end

Article.find_fulltext({:col1 => ["hoge moge", "hoho"]})
 # => SELECT * FROM models WHERE col1 @@ '*D+ hoge moge OR hoho';

Article.find_fulltext({:col1 => "hoge", :col2 => ["moge", "hoho"]}, :all => true)
 # => SELECT * FROM models WHERE col1 @@ '*D+ hoge' OR col2 @@ '*D+ moge OR hoho';

 # Snippet
Article.find_fulltext({:col1 => "hoge moge"}, :snippet => true)
Article.find_fulltext({:col1 => "hoge moge"}, :snippet => {:length => 45, :decorations => ['<em>', '</em>'])
Article.find_fulltext({:col1 => "hoge moge"}, :snippet => true, :css => {:class => "other_ludia_class"})
