• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - thanh tung cua nhung cong ((((van tan) OR (van tuan))) OR (van thanh)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh tung cua nhung cong ((((van tan) OR (van tuan))) or (van thanh)) cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - thanh tung cua nhung cong ((((van tan) OR (van tuan))) or (van thanh)) cao*.
