• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chau tinh) OR (((ha tinh) OR (may tinh)))) - thanh tung nghe thong cong tac van ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chau tinh) or (((ha tinh) OR (may tinh)))) - thanh tung nghe thong cong tac van ban*".
