Maybe there are, I don't know the numbers on that, but your earlier post seemed to suggest that every cell in the body, not just the gonads, contributes. It does not.
As for your use of the word, "search", I don't think that is the best word to use, unless you are into obscurantism.The term has connotations of intelligence being behind it, for one thing. I understand that evolution could be viewed as a "search" for new, successful genomes, but, as I said, the danger is in the hint of intelligence behind the "search".

EDIT: Also, of the billion or do germ-line cells, producing sperm cells, very few actually get used to fertilise an egg cell, so the numbers you are citing are inappropriately large, unless you have billions of babies.
