Checking for a given phrase in an expression

Hello everyone

Is it possible to ask Mathematica to check if a given phrase occurs in
an expression? Say I have

aa = 1 + x + x y + Log[Sin[z]]

and

bb = x + Log[Sin[z]]

Can Mathematica tell me such a phrase bb exists in aa? Can it tell me
its 'position' within the expression aa?

Thanks for the help!
