• Performing a fuzzy search may retrieve terms with similar spellings: so sach y nang xa hoi. hieu van ((cac xuc) or (cam xuc)) va thanh ((hai cuu) OR (hai cuc)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach y nang xa hoi. hieu van ((cac xuc) OR (cam xuc)) va thanh ((hai cuu) OR (hai cuc)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach y nang xa hoi. hieu van ((cac xuc) or (cam xuc)) va thanh ((hai cuu) OR (hai cuc)) tre*".
