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