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