• If you are trying to use Boolean operators, they must be ALL CAPS: doc sach y ((dang cay) OR (dang ca)) phoi. hieu ((ve cac) OR (va cac)) nuoc may trinh ve cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc sach y ((dang cay) OR (dang ca)) phoi. hieu ((ve cac) or (va cac)) nuoc may trinh ve cua triet*".
