• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (te sach)) ky nang x hoi. hieu ((ve cham) OR (va cham)) duc va hoang hai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (te sach)) ky nang x hoi. hieu ((ve cham) OR (va cham)) duc va hoang hai cua te~".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (te sach)) ky nang x hoi. hieu ((ve cham) OR (va cham)) duc va hoang hai cua te*.
