title: Mixing ActiveRecord find Conditions
body: <p>I want to find records on a combination of created_on >= some date AND name IN some list of names.</p>
  
  <p>For ">=" I'd have to use sql condition. For "IN" I'd have to use a hash of conditions where the key is :name and the value is the array of names.</p>
  
  <p>Is there a way to combine the two?</p>
