• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu manh) OR (chieu sang)) - hanh chinh quan nhung cong ((ban than) OR (van thanh)) cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (chieu sang)) - hanh chinh quan nhung cong ((ban than) OR (van thanh)) cap~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chieu sang)) - hanh chinh quan nhung cong ((ban than) OR (van thanh)) cap*.
