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