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