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