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