• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((ly vang) or (ty xang)) xa hoi. hieu van cam ((xuc van) OR (luc van)) thanh de cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ly vang) OR (ty xang)) xa hoi. hieu van cam ((xuc van) OR (luc van)) thanh de cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ly vang) or (ty xang)) xa hoi. hieu van cam ((xuc van) OR (luc van)) thanh de cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ly vang) or (ty xang)) xa hoi. hieu van cam ((xuc van) OR (luc van)) thanh de cua te*.
