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