• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - ((hanh trang) OR (hanh trinh)) cua thong thuong ((san hang) OR (ban hang)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - ((hanh trang) OR (hanh trinh)) cua thong thuong ((san hang) or (ban hang)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - ((hanh trang) OR (hanh trinh)) cua thong thuong ((san hang) or (ban hang)) cau*.
