• If you are trying to use Boolean operators, they must be ALL CAPS: ho chu tinh - hanh trung ((qua dung) OR (qua song)) ((song van) OR (cong san)) toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chu tinh - hanh trung ((qua dung) OR (qua song)) ((song van) or (cong san)) toan cao".
