• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - hanh ((trung cua) OR (((trung tuan) OR (tran tuan)))) thong cong tan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - hanh ((trung cua) or (((trung tuan) OR (tran tuan)))) thong cong tan toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - hanh ((trung cua) or (((trung tuan) OR (tran tuan)))) thong cong tan toan ban*.
