• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - hanh trong cua ((((nhung cong) OR (thong cong))) OR (bang cong)) manh toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - hanh trong cua ((((nhung cong) OR (thong cong))) or (bang cong)) manh toan cao*".
