• If you are trying to use Boolean operators, they must be ALL CAPS: ho hieu lang - ((hanh tang) OR (hanh trang)) cua nhung cong ((tac phan) OR (tac pham)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho hieu lang - ((hanh tang) OR (hanh trang)) cua nhung cong ((tac phan) or (tac pham)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho hieu lang - ((hanh tang) OR (hanh trang)) cua nhung cong ((tac phan) or (tac pham)) cau*.
