Perhaps you should try some spelling variations:
computer network » computer networks
computer latest » computer test, computer laien, computer tests
computer liest » computer list, computer test, computer let
computers work » computers web
computer what » computers what, computing what, computer chapter

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: ((((computer what) OR (((computer liest) OR (computer latest))))) OR (((computers work) OR (computer network)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((computer what) or (((computer liest) or (computer latest))))) or (((computers work) OR (computer network))))".
• Adding a wildcard symbol may retrieve word variants: ((((computer what) or (((computer liest) or (computer latest))))) or (((computers work) OR (computer network))))*.
