• Performing a fuzzy search may retrieve terms with similar spellings: doc sach y nang x hoi. hieu van cam duc va ((((hanh tai) or (thanh tai))) or (hang tai)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doc sach y nang x hoi. hieu van cam duc va ((((hanh tai) OR (thanh tai))) OR (hang tai)) cua te.
• Adding a wildcard symbol may retrieve word variants: doc sach y nang x hoi. hieu van cam duc va ((((hanh tai) or (thanh tai))) or (hang tai)) cua te*.
