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