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