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