  The constituent counting rules, i.e., the scaling behavior of amplitudes (in
terms of the number of fundamental constituents) for exclusive processes when
high energy scales are present, have been known for decades, and have been
borne out in a number of experiments. Such scaling would be sensitive, in
particular, to possible exotic multiquark content. Here we examine how one may
use the rules to test for pentaquarks in electroproduction, or for tetraquarks
in e^+ e^- annihilation. An interesting new type of scaling (separate
Mandelstam s and t behavior) arises in the forward scattering direction. The
correct scaling arises naturally in AdS/QCD, in which the amplitudes can be
computed explicitly.
