• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh ((((chinh va) OR (hanh va))) OR (chinh tai)) nhung cong tinh toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh ((((chinh va) OR (hanh va))) or (chinh tai)) nhung cong tinh toan cau*".
