• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach tham hoa phi đong luc ) OR ( toc ((sach nganh) OR (sach ngan)) cong khi đong luc )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach tham hoa phi đong luc ) or ( toc ((sach nganh) OR (sach ngan)) cong khi đong luc ))".
• Adding a wildcard symbol may retrieve word variants: (( te sach tham hoa phi đong luc ) or ( toc ((sach nganh) OR (sach ngan)) cong khi đong luc ))*.
