We have a magento website and need ajax work for our on site search.  We use a third party search called http://www.nextopia.com

Here is what we need:

1.  Search box to have drop down recommendations as user begins typing.  Recommendations will be populated from database categories, products etc.

2.  Once search is queried we need the left nav refinements to populated and allow user to refine search.  LEft nav and product results must popluate using ajax or jquery

The shopping cart is Magento and is built on a Zend framework.
