i think the issue here is that a search is one service payed by another (adwords) and so on. for the cost of a search you have to devide all employees into their group and take out only the cost for searches. but than comes adwords and pay for it... tough the adwords code probably runs on the same servers that deliver searches (unified system)... i guess its really hard to cslculate but i would guess a search is only a fraction of a cent even before balancing it out win profits.
