Problem with TAGS, from OpenCart 1.5 to 2.0.3.1

Hello everyone,
in my old ecommerce done with OpenCart 1.5 there were function that allowed , during the loading of the product , to indicate whether it was " no milk, no salt , vegetarian, fair ... " , this work created labels ( antipixel ) in the product . Thanks to these labels user allowed, for example, search cookie " without milk " , a bread " without salt " . I would do the same thing in OpenCart 2.0 but I have more contact with the old developer for ask him the name of extension, so i can't upgrade to opencart 2.0. Someone knows an extension that does this ?
