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