• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu xanh - ((hanh tran) OR (thanh tran)) ((van phung) OR (van dong)) cong tac thanh cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu xanh - ((hanh tran) OR (thanh tran)) ((van phung) or (van dong)) cong tac thanh cao~".
• Adding a wildcard symbol may retrieve word variants: doc hieu xanh - ((hanh tran) OR (thanh tran)) ((van phung) or (van dong)) cong tac thanh cao*.
