• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ty nang mai hoi. lieu va tai ((tuc va) or (truc va)) ((danh dau) OR (danh tu)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ty nang mai hoi. lieu va tai ((tuc va) OR (truc va)) ((danh dau) OR (danh tu)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ty nang mai hoi. lieu va tai ((tuc va) or (truc va)) ((danh dau) OR (danh tu)) cua triet".
• Adding a wildcard symbol may retrieve word variants: toc sach ty nang mai hoi. lieu va tai ((tuc va) or (truc va)) ((danh dau) OR (danh tu)) cua triet*.
