• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) OR (su sach)) y nang xa hoi. hieu ve ((cam luc) or (cau luc)) va hanh cua cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (su sach)) y nang xa hoi. hieu ve ((cam luc) OR (cau luc)) va hanh cua cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (su sach)) y nang xa hoi. hieu ve ((cam luc) or (cau luc)) va hanh cua cua triet".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) OR (su sach)) y nang xa hoi. hieu ve ((cam luc) or (cau luc)) va hanh cua cua triet*.
