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