• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tieu danh) OR (tiep danh)) - anh tang cam nang cong van ((toan cau) OR (toan ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu danh) OR (tiep danh)) - anh tang cam nang cong van ((toan cau) or (toan ban))".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu danh) OR (tiep danh)) - anh tang cam nang cong van ((toan cau) or (toan ban))*.
