• Performing a fuzzy search may retrieve terms with similar spellings: te sach y tang ma hoi. hieu va cham loc va ((((danh cau) OR (danh dau))) or (danh ca)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y tang ma hoi. hieu va cham loc va ((((danh cau) OR (danh dau))) OR (danh ca)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y tang ma hoi. hieu va cham loc va ((((danh cau) OR (danh dau))) or (danh ca)) cua triet".
