No research, but some common sense from a product point of view. "Google custom search" is the default suggested by Google. Google does not encourage changing it. Don't read too much into it - don't assume they considered changing it.
Google custom search usually replaces internally maintained search. In that case, the prompt's usefulness is in alerting users to expect different results format. Even if it discourages searches, consider that when replacing internal searches in a working website, implementing Google search may increase the success rate of searches considerably (this is easy to measure). This may outweigh some marginal difficulty (and one that's tough to measure). Last comment: "Google custom search" is a particularly obnoxious display (what with the oversized color logo and a symbol character to top!). A short message, containing only an instruction or sample search, may work better (assuming it disappears on any focus). . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
