Perhaps you should try some spelling variations:
ilo world » halo world, two world, wto world
de images » de imagens, de imagem, we images
2008 ilo » 2008 iso, 2008 pilot, 2008 iet
de image » de imagem, de imagen, die image

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 ilo world ((de image) OR (de images)) ((session three) OR (session types)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "2008 ilo world ((de image) or (de images)) ((session three) OR (session types))".
• Adding a wildcard symbol may retrieve word variants: 2008 ilo world ((de image) or (de images)) ((session three) OR (session types))*.
