• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu xanh - hanh ((trang cua) OR (tang cua)) dung cong van ((tuan cap) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu xanh - hanh ((trang cua) or (tang cua)) dung cong van ((tuan cap) OR (than cap))~".
• Adding a wildcard symbol may retrieve word variants: doc hieu xanh - hanh ((trang cua) or (tang cua)) dung cong van ((tuan cap) OR (than cap))*.
