• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach tu nang x hoi. hieu ve pham duy va ((hanh di) OR (((hang doi) OR (hang di)))) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach tu nang x hoi. hieu ve pham duy va ((hanh di) or (((hang doi) OR (hang di)))) cua triet".
• Adding a wildcard symbol may retrieve word variants: vu sach tu nang x hoi. hieu ve pham duy va ((hanh di) or (((hang doi) OR (hang di)))) cua triet*.
