• If you are trying to use Boolean operators, they must be ALL CAPS: thep lieu tinh - canh ((doanh cua) OR (doanh luan)) thong cong manh ((tuan cau) OR (toan cau)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thep lieu tinh - canh ((doanh cua) OR (doanh luan)) thong cong manh ((tuan cau) or (toan cau))".
• Adding a wildcard symbol may retrieve word variants: thep lieu tinh - canh ((doanh cua) OR (doanh luan)) thong cong manh ((tuan cau) or (toan cau))*.
