• Performing a fuzzy search may retrieve terms with similar spellings: ((su sac) OR (su xac)) ky dang van hoi. ((hieu ve) or (hieu va)) cao duc van lanh hai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su xac)) ky dang van hoi. ((hieu ve) OR (hieu va)) cao duc van lanh hai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su xac)) ky dang van hoi. ((hieu ve) or (hieu va)) cao duc van lanh hai cua triet".
• Adding a wildcard symbol may retrieve word variants: ((su sac) OR (su xac)) ky dang van hoi. ((hieu ve) or (hieu va)) cao duc van lanh hai cua triet*.
