• If you are trying to use Boolean operators, they must be ALL CAPS: vu cac ky ((lang van) OR (dang van)) hoi. hieu ((van cac) OR (van chat)) 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 (dang van)) hoi. hieu ((van cac) or (van chat)) luc va thanh ho cua tre*".
