Search by product attribute

[Russell37uk]

Hi,
Apologies if posted in the wrong board.

I know there are a few paid extensions available, but wanted to know if there is a free extension available (or if its already built into) Abantecart.
I am using the latest version 1.2.13

I want to know if its possible / how to let my customers search products by attribute?, eg by colour, size, price range etc

Thanks
