The FindAll method searches the domain specified in the principal context for objects that have identical properties to those set on the query filter. The FindAll method returns all objects that match the supplied object whereas the FindOne method returns only a single matching principal object. http://msdn.microsoft.com/en-us/library/bb384378(v=vs.90).aspx

I don't know what you need, but you could do a search by 1 proprety and 1 by other and then use LINQ on the lists to merge,filter and etc...
