This looks like a good place to use ^match and Vmatch.  I've used this
only once of twice but it can definately do what you want.  e.g.

<< { '&a AND NOT &a' '0' } ^MATCH >>

Would be the second example.

But I don't have much insight as to when to use ^MATCH as oppose to
VMATCH.  I understand (sorta) how they differ but don't understand
when to use one or the other.  Anyone care to comment?
