• If you are trying to use Boolean operators, they must be ALL CAPS: (( do danh thanh hoa thi đong luc ) OR ( ((tu sach) OR (thu sach)) ngan hoa phi đong luc ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( do danh thanh hoa thi đong luc ) or ( ((tu sach) OR (thu sach)) ngan hoa phi đong luc ))~".
• Adding a wildcard symbol may retrieve word variants: (( do danh thanh hoa thi đong luc ) or ( ((tu sach) OR (thu sach)) ngan hoa phi đong luc ))*.
