• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty hang va hoi. hieu ((ve cam) OR (ve cham)) ((duc va) OR (duc tan)) hanh lai chau triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty hang va hoi. hieu ((ve cam) OR (ve cham)) ((duc va) or (duc tan)) hanh lai chau triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ty hang va hoi. hieu ((ve cam) OR (ve cham)) ((duc va) or (duc tan)) hanh lai chau triet*.
