[Xapian-discuss] Sticky results

[QE :: Felix Ostmann]

You simple need another value with sticky true-false i think:

Xapian::MultiValueKeyMaker
sorter;sorter.add_value(3);sorter.add_value(1,
true);enquire.set_sort_by_key(&sorter, true);Xapian::MSet mset =
enquire.get_mset(0, 10);



Mit freundlichem Gruß
