• If you are trying to use Boolean operators, they must be ALL CAPS: vu cac ky ((((lang van) OR (giang van))) OR (tang van)) hoi. thien van cac luc va thanh ho cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu cac ky ((((lang van) OR (giang van))) or (tang van)) hoi. thien van cac luc va thanh ho cua tre*".
