• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (ho chieu)) xanh - anh thong va hang cong ((anh toan) OR (anh tuan)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (ho chieu)) xanh - anh thong va hang cong ((anh toan) OR (anh tuan)) tap~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (ho chieu)) xanh - anh thong va hang cong ((anh toan) OR (anh tuan)) tap*.
