• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (((chieu sang) OR (hieu lang)))) - anh tang cua cong nong van nhan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (((chieu sang) OR (hieu lang)))) - anh tang cua cong nong van nhan ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (((chieu sang) OR (hieu lang)))) - anh tang cua cong nong van nhan ban*.
