But it is expected to ignore my OR and convert that to a "regular" term?

if I omit the OR it produces  Xapian::Query((S1 AND S2))

I have     $self->qp->set_default_op(OP_AND);

in my setup, but commenting it out does no difference.


Is this a documentation problem, or a code-problem?

If its a documentation problem, is there any way to achive what I am  
trying to do?
