search bring up global search. This still respects the case where an app has chosen to disable search entirely by overriding onSearchRequested() to return false. I do not believe any changes to the SearchManager documentation (http://developer.android.com/reference/android/app/SearchManager.html#HowSearchIsInvoked) are necessary, because this documentation already indicates that pressing the search button within an app that does nothing special with regard to search can bring up global search.
