• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc nganh) OR (hoc nhanh)) ky lang van hoi. ((hieu ve) or (lieu va)) cac duc va nhanh ha cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc nganh) OR (hoc nhanh)) ky lang van hoi. ((hieu ve) OR (lieu va)) cac duc va nhanh ha cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc nganh) OR (hoc nhanh)) ky lang van hoi. ((hieu ve) or (lieu va)) cac duc va nhanh ha cua te".
• Adding a wildcard symbol may retrieve word variants: ((hoc nganh) OR (hoc nhanh)) ky lang van hoi. ((hieu ve) or (lieu va)) cac duc va nhanh ha cua te*.
