• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh trang cua ((nhung cong) OR (thong thong)) ban ((thanh ban) OR (thanh van))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh trang cua ((nhung cong) or (thong thong)) ban ((thanh ban) OR (thanh van))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh trang cua ((nhung cong) or (thong thong)) ban ((thanh ban) OR (thanh van))*.
