Schmutz in schmutz out! If you key in schmutz (and do a good enough job of it to fool the SafeSearch) then guess what results you get – schmutz :).
If you key in what you need for your work, or better yet divrei Torah, you get what you ask for as well.
The one problem that does occur when using any search engine to find divrei Torah is that nonsense, LH, MSR and kefira written by all kinds of malcontents or self appointed scholars are thrown in with the kosher divrei Torah. Sadly, key in the name of any of the Gedoilei Torah who lived from hmmm..the time the “Haskalah” started until now and you will see what I mean :(.
