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