• If you are trying to use Boolean operators, they must be ALL CAPS: te san ky ((nang ma) OR (tang ma)) hoi. hieu ve cham soc ((ban nhan) OR (van nhan)) vien cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te san ky ((nang ma) or (tang ma)) hoi. hieu ve cham soc ((ban nhan) OR (van nhan)) vien cua tu".
• Adding a wildcard symbol may retrieve word variants: te san ky ((nang ma) or (tang ma)) hoi. hieu ve cham soc ((ban nhan) OR (van nhan)) vien cua tu*.
