• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach ha me giai co thong tin ) OR ( toc sach ha kem gian ((con thong) OR (con hong)) minh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach ha me giai co thong tin ) or ( toc sach ha kem gian ((con thong) OR (con hong)) minh ))~".
• Adding a wildcard symbol may retrieve word variants: (( su sach ha me giai co thong tin ) or ( toc sach ha kem gian ((con thong) OR (con hong)) minh ))*.
