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