One of the spell reference documents circulating arround notes whether the spell in anonymous or not.
However, I am sorry that I do not recall which one it actually is. Just check the usual download sites and look for a spreadsheet which is colored and has different pages for different spell type. The "ranged attack"-spell pages is the one you want to look at. So I cannot help you with your search, but I can tell you that your search is not hopeless...
