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