• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach ky) OR (sach ty)) nang xa hoi. hieu ((ve cam) OR (ve cham)) luc van hanh cua cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach ky) OR (sach ty)) nang xa hoi. hieu ((ve cam) or (ve cham)) luc van hanh cua cua triet".
• Adding a wildcard symbol may retrieve word variants: so ((sach ky) OR (sach ty)) nang xa hoi. hieu ((ve cam) or (ve cham)) luc van hanh cua cua triet*.
