• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((nhieu tang) OR (nhiet nang)) - hanh trinh cua nhung cong san ((thanh cham) OR (thanh cha))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((nhieu tang) or (nhiet nang)) - hanh trinh cua nhung cong san ((thanh cham) OR (thanh cha))~".
• Adding a wildcard symbol may retrieve word variants: doc ((nhieu tang) or (nhiet nang)) - hanh trinh cua nhung cong san ((thanh cham) OR (thanh cha))*.
