• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky ((nang co) or (lang ra)) hoi. hieu qua cam tuc va ((danh di) OR (danh du)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky ((nang co) OR (lang ra)) hoi. hieu qua cam tuc va ((danh di) OR (danh du)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky ((nang co) or (lang ra)) hoi. hieu qua cam tuc va ((danh di) OR (danh du)) cua te".
• Adding a wildcard symbol may retrieve word variants: vu sach ky ((nang co) or (lang ra)) hoi. hieu qua cam tuc va ((danh di) OR (danh du)) cua te*.
