Thanks Olly,

When I remove the quotes I get the following fatal error when running Perl's
(often recommended) strict pragma:

  [error] Bareword "Search::Xapian::QueryParser::OP_AND" not allowed while
"strict subs" in use

Just setting it to zero works though I'm not sure if that's by coincidence.

  $qp->set_default_op( 0 );

Search::Xapian mentions:

OP_AND
OP_OR
OP_AND_NOT
OP_XOR
OP_AND_MAYBE
OP_FILTER
OP_NEAR
OP_PHRASE
OP_ELITE_SET

In what file can I get the numeric value for each of these and will setting
set_default_op to a number work?

Thanks.
