• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) OR (sac ky)) nang o lai. lieu va ((cam truc) or (nam truc)) va thanh lai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sac ky)) nang o lai. lieu va ((cam truc) OR (nam truc)) va thanh lai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sac ky)) nang o lai. lieu va ((cam truc) or (nam truc)) va thanh lai cua triet".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) OR (sac ky)) nang o lai. lieu va ((cam truc) or (nam truc)) va thanh lai cua triet*.
