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