• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chu xanh) OR (chu manh)) - anh ((tang cua) or (hang ca)) thong thong trinh toan ban~".
• Adding a wildcard symbol may retrieve word variants: cho ((chu xanh) OR (chu manh)) - anh ((tang cua) or (hang ca)) thong thong trinh toan ban*.
