• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ky lang xa hoi. lieu va cam ((luc va) or (tuc va)) ((thanh tri) OR (chinh tri)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ky lang xa hoi. lieu va cam ((luc va) OR (tuc va)) ((thanh tri) OR (chinh tri)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ky lang xa hoi. lieu va cam ((luc va) or (tuc va)) ((thanh tri) OR (chinh tri)) cua triet".
• Adding a wildcard symbol may retrieve word variants: toc sach ky lang xa hoi. lieu va cam ((luc va) or (tuc va)) ((thanh tri) OR (chinh tri)) cua triet*.
