I am trying to learn Couch so what doesn't make sense of the "or"?

  Your "or" doesn't make sense there.  You can do it with or without a view
and in either case you can do it in one request.

  It looks like you can probably just use alldocs with a start and end key
specified limiting to the doc IDs that start with "product-".

  You could also build a view that maps sku -> [something] for all documents
of type product and then traverse that.  The value could be null, or
something you might want to know when looking at a sku.

  Or if you have different ways of looking at products, you could use that
as the key and the sku as the value and chop it up more neatly from there.
