• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu xanh) OR (chieu tinh))) OR (lieu tinh)) - thanh tung va nhung cong tac toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu xanh) OR (chieu tinh))) or (lieu tinh)) - thanh tung va nhung cong tac toan tap*".
