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