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