• The words AND, OR and NOT may confuse the search; try adding quotes: "((tho cua) OR (tho ca)) tinh - hanh tranh cua dong thong dan ((toan cau) OR (van ban))~".
• Adding a wildcard symbol may retrieve word variants: ((tho cua) OR (tho ca)) tinh - hanh tranh cua dong thong dan ((toan cau) OR (van ban))*.
