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