• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((((hieu lang) OR (hieu quang))) OR (chieu sang)) - hanh trung va nhung tuong dang hanh ca*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((hieu lang) OR (hieu quang))) or (chieu sang)) - hanh trung va nhung tuong dang hanh ca*".
