I found default search of virtuemart/joomla not good at all so I was in search of good search module and my search ends at Virtuemart Products Ajax Search. Excellent module and on that excellent customer service is like icing on the cake. Mr. Dang Thuc Dam is very friendly and he himself set this up on my website. All I can say amazing customer support and amazing search module. Do not think twice before getting this module, just go and get it.
