• Performing a fuzzy search may retrieve terms with similar spellings: te sach thi ((nang xa) OR (nang ma)) hoi. hieu ve cac xuc van hanh vai ((cua cu) or (cua chu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thi ((nang xa) OR (nang ma)) hoi. hieu ve cac xuc van hanh vai ((cua cu) OR (cua chu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thi ((nang xa) OR (nang ma)) hoi. hieu ve cac xuc van hanh vai ((cua cu) or (cua chu))".
• Adding a wildcard symbol may retrieve word variants: te sach thi ((nang xa) OR (nang ma)) hoi. hieu ve cac xuc van hanh vai ((cua cu) or (cua chu))*.
