It seem the docstring of "ufunc" is not in the html build of the docs:

In [5]: from numpy import ufunc

In [6]: 'whole array' in ufunc.__doc__
Out[6]: True

If I grep the html build for "whole array" there is no results...

ufunc doc is set in numpy/core/_add_newdocs.py, like other things so there is no reason for it not to be built, it likely miss a entry in generated API ? Am I really bad at searching ? Or maybe that's on purpose.
