• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh trang cua dang ((nong dan) OR (nguong dan)) ((tran ban) OR (tranh ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh trang cua dang ((nong dan) OR (nguong dan)) ((tran ban) or (tranh ban))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh trang cua dang ((nong dan) OR (nguong dan)) ((tran ban) or (tranh ban))*.
