• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chua) OR (ho chua)) xang - hanh ((tang cua) OR (hang cua)) nhung cong manh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chua) or (ho chua)) xang - hanh ((tang cua) OR (hang cua)) nhung cong manh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((theo chua) or (ho chua)) xang - hanh ((tang cua) OR (hang cua)) nhung cong manh toan ban*.
