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