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