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