• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((y tang) or (7 tang)) ma hoi. hieu ve cham ((luc va) OR (loc va)) danh cau cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y tang) OR (7 tang)) ma hoi. hieu ve cham ((luc va) OR (loc va)) danh cau cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y tang) or (7 tang)) ma hoi. hieu ve cham ((luc va) OR (loc va)) danh cau cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ((y tang) or (7 tang)) ma hoi. hieu ve cham ((luc va) OR (loc va)) danh cau cua triet*.
