• Performing a fuzzy search may retrieve terms with similar spellings: (( su sach ((bai me) OR (mai me)) giao cong khong minh ) or ( su sach bai de giai con thong minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach ((bai me) OR (mai me)) giao cong khong minh ) OR ( su sach bai de giai con thong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach ((bai me) OR (mai me)) giao cong khong minh ) or ( su sach bai de giai con thong minh ))".
• Adding a wildcard symbol may retrieve word variants: (( su sach ((bai me) OR (mai me)) giao cong khong minh ) or ( su sach bai de giai con thong minh ))*.
