Option as a Product is showing in Joomla search

-- url of the page with the problem -- : uhansworkwear.com/component/search/?sear...hrase=all&Itemid=101
-- HikaShop version -- : 2.3.3
-- Joomla version -- : 3.3.4
-- PHP version -- : 5.4.33
-- Browser(s) name and version -- : Firefox 31

I have Hika Shop Essential and I've created options called Big&Tall. When we do a search for a product in the Joomla core search, both the main product shows up and the Big&Tall option shows up. So you can essentially click on the Big&Tall option and it will take you to the page.
We don't want the Big&Tall option to show up in search as a separate product since it is not a separate product. It is a Big&Tall option for another product.
How can we stop the "options" from showing up in search?
Thanks again for your help.

Okay, that seems to have taken care of the problem. Thanks so much.
