I use it for my virtuemart store ( 9000 products ) and I like the popunder that gives you the results as you type.
It has a nice interface, blends with the template very nicely, and is 10000% customiseable.
The only downside could be that it's a bit harsh on the server load with the live function it has, and that it doesn't display out of stock products when you search for them as an administrator.
Overall, it is a GREAT extension, and its price is very good too!
thank you for your review!
As you can see on our site there is a Support system, where you can ask questions about the products.
If you make a ticket there, we can help you to find this not Universal AJAX Live Search related setting. I think it will be a Virtuemart option.
