I don't think I understand buzz search. For example I specify salmon in search with buzz. I get those recipes with fewer notes showing up ahead of ones which should be higher. 0 buzz showing up before 1 buzz or 1 buzz showing up before 2 buzz.
Buzz is a sort that adds together the number of ratings and the number of comments. So you may well see a recipe with zero comments showing above one with 1 comment if the first recipe has more ratings.
