• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach ((bai me) OR (ba me)) gioi con thong minh ) OR ( so sach ha me giai san trong tinh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach ((bai me) OR (ba me)) gioi con thong minh ) or ( so sach ha me giai san trong tinh ))~".
• Adding a wildcard symbol may retrieve word variants: (( thu sach ((bai me) OR (ba me)) gioi con thong minh ) or ( so sach ha me giai san trong tinh ))*.
