Thank you very much for the input Indeed there are problems with any search but it is the only tool we have and it has been brought so often in all discussions As for nonenglish titles I did an extensive random testing of the results and I didnt notice but very few nonenglish titles There were many translations from usually German I think it is not impossible to screen out the irrelevant hits without resorting to manual handpicking Even if you add more  terms like those you mentioned above and a few more the count is  It is drastically reduced to  if you add pope not fair at all but it is not affected if you add pope Julian So I think the count is well over  Even if you still dont trust the search because of the ambiguity of the name search for the following  Emperor Julian OR Julian the emperor OR Julian emperor JuliantheApostate It gets  occurrences Are you still not convinced As for the also known as the Apostate it does strengthen the reasoning of the supporters of Julian the Apostate it is the plain name with a clearly neutralized the also known as suffix Similar to the parentheses above
