in what way does shear stress differ from direct stress?

A direct shear stress would be that across a hot-head rivet. Or when punching a hole in something with a tool. Or, in a simple form, when cutting paper. The load is applied directly in the direction of the intended shear. It is to cut.
Indirect shear occurs when a load is not directly acting in the direction of the shear. This is probably the most common form of shear stress.
An example would be two items bolted together without the bolt having any pre-load. A larger example is a beam. At the supports, the bending moment is often translated into a shear stress. Finally, if a material is compressed to failure
