• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu xanh) OR (((chieu sang) OR (chieu xanh)))) - nang hang ca hang cong tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (((chieu sang) OR (chieu xanh)))) - nang hang ca hang cong tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (((chieu sang) OR (chieu xanh)))) - nang hang ca hang cong tan toan cau*.
