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