Order in Google arguments

Does Google give a different answer if you reorder the words in the search? What? A trivial question? Have you ever tried to refine a search by reordering the words? Wouldn't it be useful if you knew for sure that it would or would not make a difference?

Experiment:

ruby rails bureaucrat gem examples


rails bureaucrat gem examples ruby

These two searches indeed did produce different results! And not just a reordering of the results. There were at least two results in the top 7 which were present in one and not the other.
