title: Magento - configurable products not showing up when searching
body: <p>When I search for a configurable product (by name, name fragment or SKU) the search does not return any configurable products. I can search for simple products.</p>
  
  <p>The configurable products;</p>
  
  <ul>
  <li>Are in stock</li>
  <li>Are set to "catalogue / search" visibility</li>
  <li>Are visible in the categories and are purchasable</li>
  </ul>
  
  <p>This is a multi-store setup and this issue only affects one store, so I'm assuming it's a configuration issue, but I can't find any setting that might stop configurable products being returned in a search.</p>
  
  <p>I'm open to suggestions on this one, I'm pretty sure I've overlooked something silly - I just can't work out what!</p>
