• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach ha me thai hoc thong tin ) OR ( su ((sach phan) OR (mach phan)) ve gioi co buong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach ha me thai hoc thong tin ) or ( su ((sach phan) OR (mach phan)) ve gioi co buong tin ))".
• Adding a wildcard symbol may retrieve word variants: (( thu sach ha me thai hoc thong tin ) or ( su ((sach phan) OR (mach phan)) ve gioi co buong tin ))*.
