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