• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((tu hang) OR (thu hang)) xa hoi. hieu ((ve cham) OR (ve chat)) duc va thanh hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((tu hang) OR (thu hang)) xa hoi. hieu ((ve cham) or (ve chat)) duc va thanh hai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((tu hang) OR (thu hang)) xa hoi. hieu ((ve cham) or (ve chat)) duc va thanh hai cua tre*.
