How do the candidates know _what_ to search? That's memorisation.
How do you get creativity, how are candidates better able to combine idea together? By forming each idea into a memory 'chunk' that can be handled as a single concept, and then working to combine these chunks.
If you hire people who can search google, then you get people who can search what is easily searchable, and who can create what has been previously posted online. If they somehow have 'internal' knowledge and capability, that's memory.
