• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty hang xa hoi. ((hieu ve) OR (hieu va)) chau phu va ((hanh hai) OR (hang hai)) van trieu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty hang xa hoi. ((hieu ve) or (hieu va)) chau phu va ((hanh hai) OR (hang hai)) van trieu*".
