Hi guys
I met a customer and need to get back to him on a requirement he has. He has 2 websites. One for the catalog and another for the e-commerce. Not are in 2 separate domains. So looking into merging both domains into one but he wants to keep some functionality of the catalog without affecting the e-commerce. So here it goes:

- he as product families. These are not categories. But somehow related products because they are very similar in size. 
- so when his customer searches a product, the customer should see a product family

Example:

product A and B are  from the Corners category.
Product X and Y are from the Corners category

So if the customer searches for 'corner' all these would come up. But if he searches for B the A and B would come up. 

So, A and B would be grouped in a box and X and Y would be grouped in another box. 

Hope that makes sense. Hope you can guide me in the right direction.
