• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach y nang ma hoi. hieu ((ve cam) OR (ve cham)) ((tuc va) OR (tuc xa)) thanh loi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach y nang ma hoi. hieu ((ve cam) or (ve cham)) ((tuc va) OR (tuc xa)) thanh loi cua triet*".
