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