• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach v ((nang xa) OR (lang xa)) hoi. lieu va cao luc ((va danh) or (va dinh)) di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach v ((nang xa) OR (lang xa)) hoi. lieu va cao luc ((va danh) OR (va dinh)) di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach v ((nang xa) OR (lang xa)) hoi. lieu va cao luc ((va danh) or (va dinh)) di cua tre".
• Adding a wildcard symbol may retrieve word variants: thuoc sach v ((nang xa) OR (lang xa)) hoi. lieu va cao luc ((va danh) or (va dinh)) di cua tre*.
