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