• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((nang xa) OR (nang x)) hoi. hieu hieu ((lua nuoc) OR (luat duoc)) va danh dai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((nang xa) or (nang x)) hoi. hieu hieu ((lua nuoc) OR (luat duoc)) va danh dai cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((nang xa) or (nang x)) hoi. hieu hieu ((lua nuoc) OR (luat duoc)) va danh dai cua triet*.
