• Performing a fuzzy search may retrieve terms with similar spellings: bo sach ((thu nang) or (thu bang)) cao hoi. hieu ((v pham) OR (d pham)) chuc va hanh lai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: bo sach ((thu nang) OR (thu bang)) cao hoi. hieu ((v pham) OR (d pham)) chuc va hanh lai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "bo sach ((thu nang) or (thu bang)) cao hoi. hieu ((v pham) OR (d pham)) chuc va hanh lai cua te".
• Adding a wildcard symbol may retrieve word variants: bo sach ((thu nang) or (thu bang)) cao hoi. hieu ((v pham) OR (d pham)) chuc va hanh lai cua te*.
