Something like this (totally untested) program:

#include <xapian.h>
#include <iostream>
using namespace std;

int main(int argc, char ** argv) {
    if (!argv[1]) exit(1);
    Xapian::Database db = Xapian::Auto::open(argv[1]);
    TermIterator t = db.allterms_begin();
    const TermIterator end = db.allterms_end();
    t.skip_to("Q");
    while (t != end) {
	if ((*t)[0] != 'Q') break;
	cout << *t << endl;
	++t;
    }
}
