• If you are trying to use Boolean operators, they must be ALL CAPS: ho hieu lang - thanh tung cua tong trong van ((((than cua) OR (ban cua))) OR (khan cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho hieu lang - thanh tung cua tong trong van ((((than cua) OR (ban cua))) or (khan cap))~".
• Adding a wildcard symbol may retrieve word variants: ho hieu lang - thanh tung cua tong trong van ((((than cua) OR (ban cua))) or (khan cap))*.
