• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu nganh) OR (((chieu sang) OR (chieu sach)))) - hanh trung cua nhung huong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu nganh) or (((chieu sang) OR (chieu sach)))) - hanh trung cua nhung huong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu nganh) or (((chieu sang) OR (chieu sach)))) - hanh trung cua nhung huong dan toan cau*.
