! and % are the proximity operators of CCL, ISO 8777:1993(E).
! is for precise word order. ! alone is for immediate adjacency in the order
entered. !n is for specifying the maximum distance (in words).
% shall be used between words when word order is not to be specified.
So use ! and % as proximity operators if it is important to keep CQL as
close as possible to CCL. This is my personal preference, but I can live
with W/ and N/.
