• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (so sanh)) ky ((dinh xa) OR (dinh xu)) hoi. hieu van lam tuc va tinh ve cua viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (so sanh)) ky ((dinh xa) OR (dinh xu)) hoi. hieu van lam tuc va tinh ve cua viet~".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (so sanh)) ky ((dinh xa) OR (dinh xu)) hoi. hieu van lam tuc va tinh ve cua viet*.
