I'm not so sure. By 'search' we're talking about a class of approaches
that progressively enumerate points in a space in some way. But I think
that the space of all ideas isn't enumerable - it's
real-valued/uncountable - so a 'search' approach could, at best, be
operating on an limited-precision abstraction of it. Creating knowledge,
by contrast, doesn't need to have limited precision.

Evolution consists of conjecture (variation) and refutation (selection),
which Popper claimed is the only means by which knowledge can be
created. I'm not sure whether it's "thinking" but it definitely meets
the criteria for knowledge-creation.

That seems a non-sequitur to me. The issue isn't about making mistakes,
it's about correcting mistakes.

Well, with zero background knowledge, neither Google the machine or Mr
Google the person would be able to filter results correctly for us. Why
do you ask?
