• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach y)) lang xa hoi. lieu va cao suc ((va danh) OR (va dan)) vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) or (sach y)) lang xa hoi. lieu va cao suc ((va danh) OR (va dan)) vi cua triet".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) or (sach y)) lang xa hoi. lieu va cao suc ((va danh) OR (va dan)) vi cua triet*.
