I think that UNION will do the trick. Perhaps you could do
selectA = 'SELECT <the fields> FROM fileA WHERE <criteria>'
selectB = 'SELECT <the fields> FROM fileB WHERE <criteria>'
order = ' ORDER BY <ordering fields>'
if (search = both A and B)
query = selectA + ' UNION ' + selectB + order
elseif (search = A only)
query = selectA + order
query = selectB + order
Would something like that do what you're after?
