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