• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty ((lang xa) OR (lang ha)) hoi. hieu ve cham ((truc va) OR (trung va)) thanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty ((lang xa) or (lang ha)) hoi. hieu ve cham ((truc va) OR (trung va)) thanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ty ((lang xa) or (lang ha)) hoi. hieu ve cham ((truc va) OR (trung va)) thanh vi cua te*.
