title: Magento: How to get products by tag name?
body: <p>I am using Magento 1.7.0.0 CE and have a few questions.</p>
  
  <p>How can i get products by tag name?</p>
  
  <p>Is there any method in Magento that takes tag name and returns products assigned to that tag (tags are made by admin and products are assigned to it)</p>
  
  <p>I ideally am looking for Mage Core API to do this. Does Mage Core API include this functionality?</p>
  
  <p>Many thanks,
  Pez</p>
