Perhaps you should try some spelling variations:
"computer works" » "computers work", "computer networks", "complete works"
"computer wird" » "computer word", "computer wie", "computer work"
"computer worm" » "computer worms", "computer word", "computer work"

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 works") OR ("computer wird"))) OR ("computer worm")).
• Removing quotes may allow a broader search: (((( computer works ) or ( computer wird ))) or ( computer worm )).
• Adding a wildcard symbol may retrieve word variants: (((("computer works") or ("computer wird"))) or ("computer worm"))*.
