Search History Not Part of the Facebook Activity Log Anymore

It seems that the Search log has been removed from the Facebook activity page. Is this linked with the coming global release of the Graph search?

It would be interesting to know the reason(s) behind such a choice. Does Facebook think it could be disturbing/embarrassing for some of its users to get a precise and chronological picture of whom & what they're looking for on this SNS, once the graph search implemented? Other motivations...
