• Performing a fuzzy search may retrieve terms with similar spellings: (( tu ((bach ha) OR (bac ha)) le giao dong thong minh ) or ( toc sach nha ve giai can hong minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu ((bach ha) OR (bac ha)) le giao dong thong minh ) OR ( toc sach nha ve giai can hong minh ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu ((bach ha) OR (bac ha)) le giao dong thong minh ) or ( toc sach nha ve giai can hong minh ))*".
