• Performing a fuzzy search may retrieve terms with similar spellings: vu bac ky nang mai hoi. lieu va tham ((nuoc van) or (luoc van)) ((anh vai) OR (anh va)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu bac ky nang mai hoi. lieu va tham ((nuoc van) OR (luoc van)) ((anh vai) OR (anh va)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu bac ky nang mai hoi. lieu va tham ((nuoc van) or (luoc van)) ((anh vai) OR (anh va)) cua triet".
• Adding a wildcard symbol may retrieve word variants: vu bac ky nang mai hoi. lieu va tham ((nuoc van) or (luoc van)) ((anh vai) OR (anh va)) cua triet*.
