Perhaps you should try some spelling variations:
visual types » virtual types, ideal types, visual tools
die primar » die primare, die primaren, der primar
iet world » net world, ict world, int world
iot world » post world, lost world, art world
die prior » die priori, diego prior, edge prior

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: 2008 ((iet world) OR (iot world)) ((((die prior) OR (die primar))) OR (((die prior) OR (die primar))i)) visual types.
• The words AND, OR and NOT may confuse the search; try adding quotes: "2008 ((iet world) or (iot world)) ((((die prior) OR (die primar))) or (((die prior) OR (die primar))i)) visual types".
• Adding a wildcard symbol may retrieve word variants: 2008 ((iet world) or (iot world)) ((((die prior) OR (die primar))) or (((die prior) OR (die primar))i)) visual types*.
