• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - canh tran ((van phuong) OR (va phuong)) ((dong toan) OR (dung toan)) ban tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - canh tran ((van phuong) OR (va phuong)) ((dong toan) or (dung toan)) ban tu~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - canh tran ((van phuong) OR (va phuong)) ((dong toan) or (dung toan)) ban tu*.
