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