• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu hang xa hoi. hieu ((ve cam) OR (va cham)) xuc va ((nhanh hai) OR (nhanh ha)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu hang xa hoi. hieu ((ve cam) or (va cham)) xuc va ((nhanh hai) OR (nhanh ha)) cua triet".
