• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) OR (tu san)) ky mang tay hoi. hieu va tham ((thuc ban) or (thu ban)) hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu san)) ky mang tay hoi. hieu va tham ((thuc ban) OR (thu ban)) hanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu san)) ky mang tay hoi. hieu va tham ((thuc ban) or (thu ban)) hanh vi cua triet*".
