Perhaps you should try some spelling variations:
research arguments » research catchments, research students, research elements
scarce document » scale document, care document, source document
handel research » channel research, panel research, hanse research
online shared » online sharing, online sales, online sale
online search » online research, line search, online searching

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((online shared) OR (online search)) scarce document ) OR ( online handel research arguments )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((online shared) OR (online search)) scarce document ) or ( online handel research arguments ))".
• Adding a wildcard symbol may retrieve word variants: (( ((online shared) OR (online search)) scarce document ) or ( online handel research arguments ))*.
