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