• Performing a fuzzy search may retrieve terms with similar spellings: vu ((khach ky) OR (thanh ky)) nang x hoi. hieu ve nam thuc ((day manh) or (day nhanh)) di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((khach ky) OR (thanh ky)) nang x hoi. hieu ve nam thuc ((day manh) OR (day nhanh)) di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((khach ky) OR (thanh ky)) nang x hoi. hieu ve nam thuc ((day manh) or (day nhanh)) di cua te".
• Adding a wildcard symbol may retrieve word variants: vu ((khach ky) OR (thanh ky)) nang x hoi. hieu ve nam thuc ((day manh) or (day nhanh)) di cua te*.
