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