• Performing a fuzzy search may retrieve terms with similar spellings: tu van ky nang ma hoi. lieu va pham ((duc van) OR (duc manh)) ((anh di) or (danh di)) cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu van ky nang ma hoi. lieu va pham ((duc van) OR (duc manh)) ((anh di) OR (danh di)) cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu van ky nang ma hoi. lieu va pham ((duc van) OR (duc manh)) ((anh di) or (danh di)) cua viet*".
