• Performing a fuzzy search may retrieve terms with similar spellings: su sac ((ky dang) or (ky danh)) ha noi. thien van phan duy ban hanh lam ((cua tuc) OR (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ((ky dang) OR (ky danh)) ha noi. thien van phan duy ban hanh lam ((cua tuc) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ((ky dang) or (ky danh)) ha noi. thien van phan duy ban hanh lam ((cua tuc) OR (cua tu))".
• Adding a wildcard symbol may retrieve word variants: su sac ((ky dang) or (ky danh)) ha noi. thien van phan duy ban hanh lam ((cua tuc) OR (cua tu))*.
