• If you are trying to use Boolean operators, they must be ALL CAPS: vu mach xu lang xa hoi. hieu ((van cam) OR (van lam)) luc ((va thanh) OR (ban thanh)) vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu mach xu lang xa hoi. hieu ((van cam) or (van lam)) luc ((va thanh) OR (ban thanh)) vi cua tre".
• Adding a wildcard symbol may retrieve word variants: vu mach xu lang xa hoi. hieu ((van cam) or (van lam)) luc ((va thanh) OR (ban thanh)) vi cua tre*.
