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