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