So you want to find all terms with prefix "Q" (or similar) in a
database?

If so, yes it's very easy - like so:

    Xapian::TermIterator t = db.allterms_begin();
    t.skip_to("Q");
    while (t != db.allterms_end()) {
	string unique_id = *t;
	if (unique_id[0] != 'Q') break;
	// Process unique_id
    }
