• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky ((nang xa) or (lang xa)) hoi. hieu va ((chat luc) OR (chat xuc)) va danh di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((nang xa) OR (lang xa)) hoi. hieu va ((chat luc) OR (chat xuc)) va danh di cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((nang xa) or (lang xa)) hoi. hieu va ((chat luc) OR (chat xuc)) va danh di cua tre*".
