• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh trang va thong cong van ((((nhanh cay) OR (nhanh bac))) OR (thanh mau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh trang va thong cong van ((((nhanh cay) OR (nhanh bac))) or (thanh mau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh trang va thong cong van ((((nhanh cay) OR (nhanh bac))) or (thanh mau))*.
