Doesn't say anything about it here:
And the Minecraft Wiki is one of the most reliable sources out there.
But, WARNING! If you use it you could spoil the game for yourself, I recommend only looking it up when you go insane about hours of trying to craft a certain thing and not sure how to do it.
In my case, before I started with Minecraft I already knew a few recipes and it killed a lot of fun for me that I never was able to find it out myself.
