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