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