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