• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - thanh ((tung tam) OR (vung tam)) ((thong huong) OR (thong duong)) dan toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh ((tung tam) OR (vung tam)) ((thong huong) or (thong duong)) dan toan ban".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - thanh ((tung tam) OR (vung tam)) ((thong huong) or (thong duong)) dan toan ban*.
