• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((((ty dang) OR (ty hang))) OR (thi hong)) van hoi. hieu van lam xuc va hang di cua viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((((ty dang) OR (ty hang))) or (thi hong)) van hoi. hieu van lam xuc va hang di cua viet~".
• Adding a wildcard symbol may retrieve word variants: su sach ((((ty dang) OR (ty hang))) or (thi hong)) van hoi. hieu van lam xuc va hang di cua viet*.
