• Performing a fuzzy search may retrieve terms with similar spellings: tu sach tay lang xa hoi. hieu ((ve cai) or (va cac)) xuc ((van manh) OR (van anh)) hai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tay lang xa hoi. hieu ((ve cai) OR (va cac)) xuc ((van manh) OR (van anh)) hai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tay lang xa hoi. hieu ((ve cai) or (va cac)) xuc ((van manh) OR (van anh)) hai cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach tay lang xa hoi. hieu ((ve cai) or (va cac)) xuc ((van manh) OR (van anh)) hai cua triet*.
