• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh ((tung tuan) OR (quang tuan)) phung cong ban ((thanh cap) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - thanh ((tung tuan) OR (quang tuan)) phung cong ban ((thanh cap) or (than cap))*.
