• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y sang) OR (duy sang)) ma hoi. lieu ((va cham) OR (van tham)) soc va danh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y sang) OR (duy sang)) ma hoi. lieu ((va cham) or (van tham)) soc va danh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((y sang) OR (duy sang)) ma hoi. lieu ((va cham) or (van tham)) soc va danh vi cua tre*.
