Is there any evidence that using Google Site Search will help your ranking, speed of indexing, or traffic?

[DavidButler71]

I am considering using Google Site Search on our new site. I was told...

"We have also seen a bump in traffic for sites when using Google Site Search because Google indexes the site more often (they claim using the paid Google Site Search has no effect on search rankings but we have also seen bumps in rankings after using it so that may just be what they have to say legally)."

Is there any evidence of this? Would you recommend using Google Site Search?

Thanks

This hits really high on my BS meter.
