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