• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang ((x hoi) OR (xa hoi)). hieu ((ve cam) OR (ve cac)) luc va danh tu cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang ((x hoi) or (xa hoi)). hieu ((ve cam) OR (ve cac)) luc va danh tu cua tre".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang ((x hoi) or (xa hoi)). hieu ((ve cam) OR (ve cac)) luc va danh tu cua tre*.
