• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((dang ha) OR (dung ha)) noi. ((hieu van) OR (thien van)) cham duc van hanh vai cua nuoc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky ((dang ha) OR (dung ha)) noi. ((hieu van) or (thien van)) cham duc van hanh vai cua nuoc".
• Adding a wildcard symbol may retrieve word variants: su sac ky ((dang ha) OR (dung ha)) noi. ((hieu van) or (thien van)) cham duc van hanh vai cua nuoc*.
