Xapian discuss - Nov 2007 - Search using Terms and Prefix

I am consulting the DB made by omega from PHP, then I need recovery all the
files that are pdf and talk about omega for example, my query is:

$query_string = "mime:pdf/ AND omega";
...
$qp->add_prefix("mime", "T");
...

Then I not receive any results, and have files application/pdf indexed,

Parsed query is: Xapian::Query((Tpdf:(pos=1) AND Zomega:(pos=2)))
0 results found:

Thanks

  al.

You won't. The term generated is (or should be) Tapplication/pdf - try
adding it as a boolean term. add_boolean_prefix not add_prefix? Sorry,
I know what I mean, but I'm too rushed right now to figure out if this
is the right approach. But your problem is the construction of the term.
