search work best_book image_url often no thumbnail

[Martin]

Hi,

I often get the problem that when I use search.xml, i find the works I am looking for; however 50% of the time I get "best_book" that has no thumbnail. And that is annoying since when I go on your site you have the thumbnail for that work. Could you apply one more rule that promotes the "best book" as first a book with thumbnail? Thanks.

i agree that doesn't make a lot of sense, we'll look into this.
