• Performing a fuzzy search may retrieve terms with similar spellings: thu cach tu ((sang ma) or (((nang ma) OR (mang may)))) hoi. hieu ve cam luc va hanh via cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu cach tu ((sang ma) OR (((nang ma) OR (mang may)))) hoi. hieu ve cam luc va hanh via cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu cach tu ((sang ma) or (((nang ma) OR (mang may)))) hoi. hieu ve cam luc va hanh via cua triet*".
