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