Hell o everyone,

I am working with large series and am interetsted in only retaining
certain order  terms in the expansion.  Example, I expand a
multivariate function in du and dv in an 8th order series in du and dv.
I only want to keep the terms where the order of the term is 8 or less.
Does anyone know how to do this in Mathematica?
