• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((anh hoang) OR (hanh mang)) chua dong cong van ((tuan ban) OR (luan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((anh hoang) or (hanh mang)) chua dong cong van ((tuan ban) OR (luan ban))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((anh hoang) or (hanh mang)) chua dong cong van ((tuan ban) OR (luan ban))*.
