SEARCH help: seeking 3 part choral and vocal carols...

[MisterTimMister]

I would like a search option so I can locate only 3 part carols, choral or vocal. How do I do such a search? I have tried all the search options I can find and I'm not getting results.
I am singing with a trio for a Christmas program, all sacred music. We can be a cappella or accompanied. I am fine with any 3 part configuration, SSA, SAB, ATB, whatever, I can make it work if there is something good.
3 voice Christmas. How do I do that search.
Thanks!

I'd suggest to visit The Choral Public Domain Library (CPDL) where a specific function exists, named Multi-Category Search, which may be especially useful for this kind of searches.
