• Performing a fuzzy search may retrieve terms with similar spellings: toc sach y ((nang xa) OR (nang x)) hoi. lieu va cao suc va ((danh du) or (ninh duc)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach y ((nang xa) OR (nang x)) hoi. lieu va cao suc va ((danh du) OR (ninh duc)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y ((nang xa) OR (nang x)) hoi. lieu va cao suc va ((danh du) or (ninh duc)) cua triet".
• Adding a wildcard symbol may retrieve word variants: toc sach y ((nang xa) OR (nang x)) hoi. lieu va cao suc va ((danh du) or (ninh duc)) cua triet*.
