Group by multiple columns

Hi David!

I have a little problem here, I'm using group by EAN but just found a problem in my website with it.

take a look here:

Have a look at this product: Cadac Carri Chef Deluxe, it appears three times on this page with exactly the same name because they all have a different EAN number.

Query: SELECT SQL_CALC_FOUND_ROWS * , MIN( price ) AS minPrice, MAX( price ) AS maxPrice, COUNT( id ) AS numMerchants, MATCH name AGAINST ('cadac carri chef') AS relevance FROM `pt_products` WHERE MATCH name AGAINST ('cadac carri chef') GROUP BY ean ORDER BY relevance DESC LIMIT 0,15

I searched everywhere for multiple grouping, GROUP BY ean, name should work but it doesn't..

It is now looking very confusing with exactly the same product showing multiple times.

Hope you can help me.

Cheers!
Vince.
