• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - hanh ((((tang cua) OR (hang cua))) OR (dung cua)) dang cong tinh toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - hanh ((((tang cua) OR (hang cua))) or (dung cua)) dang cong tinh toan cau*".
