 Now when you save a product, you get a _keywords field automatically:
-    
+
     p = Product.new :brand => "Apple", :name => "iPhone"
     p.tags << Tag.new(:name => "Amazing")
     p.tags << Tag.new(:name => "Awesome")
     p.tags << Tag.new(:name => "Superb")
     p.save
     => true
     p._keywords
-    
+
 Now you can run search, which will look in the _keywords field and return all matching results:
 
     Product.search("apple iphone").size
     => 1
-    
+
 Note that the search is case insensitive, and accept partial searching too:
 
     Product.search("ipho").size
     => 1
