• If you are trying to use Boolean operators, they must be ALL CAPS: te sach v nang ma hoi. ((hieu van) OR (thien van)) cam luc van ((thanh ly) OR (thanh ky)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v nang ma hoi. ((hieu van) OR (thien van)) cam luc van ((thanh ly) or (thanh ky)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach v nang ma hoi. ((hieu van) OR (thien van)) cam luc van ((thanh ly) or (thanh ky)) cua tre*.
