• If you are trying to use Boolean operators, they must be ALL CAPS: (( su ((sach ha) OR (sach xa)) me gioi binh tung manh ) OR ( su sach cha me giai cong thong tin ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su ((sach ha) OR (sach xa)) me gioi binh tung manh ) or ( su sach cha me giai cong thong tin ))~".
• Adding a wildcard symbol may retrieve word variants: (( su ((sach ha) OR (sach xa)) me gioi binh tung manh ) or ( su sach cha me giai cong thong tin ))*.
