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