• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky ((nang xa) or (((lang van) OR (dang van)))) hoi. hieu va cham xuc van hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((nang xa) OR (((lang van) OR (dang van)))) hoi. hieu va cham xuc van hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((nang xa) or (((lang van) OR (dang van)))) hoi. hieu va cham xuc van hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ky ((nang xa) or (((lang van) OR (dang van)))) hoi. hieu va cham xuc van hanh vi cua te*.
