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