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