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