• Performing a fuzzy search may retrieve terms with similar spellings: te ((((sach ky) OR (sach y))) or (sach ty)) nang xa hoi. hieu va cam xuc va hanh tai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((((sach ky) OR (sach y))) OR (sach ty)) nang xa hoi. hieu va cam xuc va hanh tai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((((sach ky) OR (sach y))) or (sach ty)) nang xa hoi. hieu va cam xuc va hanh tai cua triet".
