• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chieu sang)) - thanh truong cua thong thong tinh ((toan tap) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chieu sang)) - thanh truong cua thong thong tinh ((toan tap) OR (toan ban))*.
