• Performing a fuzzy search may retrieve terms with similar spellings: su xac ky nang x hoi. hieu ((qua chat) or (((luan phan) OR (luan van)))) xuc van thanh di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky nang x hoi. hieu ((qua chat) OR (((luan phan) OR (luan van)))) xuc van thanh di cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky nang x hoi. hieu ((qua chat) or (((luan phan) OR (luan van)))) xuc van thanh di cua tre*".
