• Performing a fuzzy search may retrieve terms with similar spellings: (( su sach ha ((me gioi) OR (me giai)) van hoang minh ) or ( tu sach phap ve gioi lam thong minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach ha ((me gioi) OR (me giai)) van hoang minh ) OR ( tu sach phap ve gioi lam thong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach ha ((me gioi) OR (me giai)) van hoang minh ) or ( tu sach phap ve gioi lam thong minh ))".
• Adding a wildcard symbol may retrieve word variants: (( su sach ha ((me gioi) OR (me giai)) van hoang minh ) or ( tu sach phap ve gioi lam thong minh ))*.
