Need to remove product pages from Search Results

I need to hide my subscription product pages from Search Results. It's easy to hide any page from Search results except for product pages. For products there is no option at all to hide them from search results.

There must be some kind of code that does this? Does anyone know how to do it? If I need a code, where would I put the code?

Any help / advice would be much appreciated!
