Ok, if I'm going to create the query for, e.g. c AND d,
what's the right way of doing that?  In particular, I
only want one logic operator, but I have to supply one
with each term.  Do I need to create both the 'c' and
'd' terms with AND, or do I put 'OR c' and 'AND d', or
is there something else what I'm missing?

Thanks,
