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