• Performing a fuzzy search may retrieve terms with similar spellings: su sach tu nong ma hoi. hieu ve pham duc va ((((hanh lai) OR (hanh tai))) or (hanh lam)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach tu nong ma hoi. hieu ve pham duc va ((((hanh lai) OR (hanh tai))) OR (hanh lam)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach tu nong ma hoi. hieu ve pham duc va ((((hanh lai) OR (hanh tai))) or (hanh lam)) cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach tu nong ma hoi. hieu ve pham duc va ((((hanh lai) OR (hanh tai))) or (hanh lam)) cua triet*.
