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