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