• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sang) OR (tiem nang)) - hanh dang ((van nhung) OR (van hung)) cong tan ran cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) or (tiem nang)) - hanh dang ((van nhung) OR (van hung)) cong tan ran cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) or (tiem nang)) - hanh dang ((van nhung) OR (van hung)) cong tan ran cau*.
