• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((thien anh) OR (thien danh)) - hanh luan van vung dong van ((than cap) OR (toan tap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thien anh) OR (thien danh)) - hanh luan van vung dong van ((than cap) or (toan tap))".
• Adding a wildcard symbol may retrieve word variants: toc ((thien anh) OR (thien danh)) - hanh luan van vung dong van ((than cap) or (toan tap))*.
