Trying to correct for MATCH ... AGAINST on top results

SELECT 
MATCH(`product_name`) AGAINST ('leica' IN BOOLEAN MODE) * 100 AS name,
MATCH(`product_category_name`) AGAINST ('leica' IN BOOLEAN MODE) * 50 AS category,
MATCH(`product_description`) AGAINST ('leica' IN BOOLEAN MODE) * 20 AS description 
FROM products  
WHERE MATCH (`product_name`, `product_category_name`, `product_description`) AGAINST ('leica' IN BOOLEAN MODE) 
ORDER BY (name)+(category)+(description) DESC LIMIT 0, 24

So this works great except in one case. When a product has 'leica' in both the name and the description, it gets bumped to the top. I would like the description to only factor in if it doesn't match in the product_name or product_category. I was thinking about adding * -5 to something, but I can't figure out how to get an accurate number to correct for what appears in the description without some kind of IF clause.

Don't add the values, use them as separate values to order by:

ORDER BY name DESC, category DESC, description DESC

Then you also don't need the multipliers.
