• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (te sach)) y ((nang xa) OR (lang xa)) hoi. hieu ve nam thuc day dinh tai cuc tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) y ((nang xa) OR (lang xa)) hoi. hieu ve nam thuc day dinh tai cuc tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) y ((nang xa) OR (lang xa)) hoi. hieu ve nam thuc day dinh tai cuc tre*".
