• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y sang ma hoi. ((((hieu ve) OR (hieu va))) OR (thien van)) cac xuc va doanh van cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y sang ma hoi. ((((hieu ve) OR (hieu va))) or (thien van)) cac xuc va doanh van cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach y sang ma hoi. ((((hieu ve) OR (hieu va))) or (thien van)) cac xuc va doanh van cua tre*.
