• Performing a fuzzy search may retrieve terms with similar spellings: truyen tho ((cac chat) OR (cao chat)) đe co ban ke y thi ((thuong cong) or (thuong dong))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: truyen tho ((cac chat) OR (cao chat)) đe co ban ke y thi ((thuong cong) OR (thuong dong)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "truyen tho ((cac chat) OR (cao chat)) đe co ban ke y thi ((thuong cong) or (thuong dong))".
• Adding a wildcard symbol may retrieve word variants: truyen tho ((cac chat) OR (cao chat)) đe co ban ke y thi ((thuong cong) or (thuong dong))*.
