• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky sang ma hoi. ((hieu van) OR (thien van)) phong duc va ((danh di) or (xanh di)) va truyen~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky sang ma hoi. ((hieu van) OR (thien van)) phong duc va ((danh di) OR (xanh di)) va truyen.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky sang ma hoi. ((hieu van) OR (thien van)) phong duc va ((danh di) or (xanh di)) va truyen".
• Adding a wildcard symbol may retrieve word variants: vu sach ky sang ma hoi. ((hieu van) OR (thien van)) phong duc va ((danh di) or (xanh di)) va truyen*.
