• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((hinh trong) OR (dinh trong)) tuan ((nhung cong) OR (pnhung cong)) tan tran cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hinh trong) OR (dinh trong)) tuan ((nhung cong) or (pnhung cong)) tan tran cau*".
