• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu xanh - hanh tang cua ((((nhung cong) OR (dung cong))) OR (hang nong)) van chat cam~.
• Adding a wildcard symbol may retrieve word variants: doc hieu xanh - hanh tang cua ((((nhung cong) or (dung cong))) or (hang nong)) van chat cam*.
