• If you are trying to use Boolean operators, they must be ALL CAPS: su sach lo lang ha hoi. hieu ((van cam) OR (van lam)) ((xuc va) OR (luc va)) thanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach lo lang ha hoi. hieu ((van cam) or (van lam)) ((xuc va) OR (luc va)) thanh vi cua triet*".
