ES seems to be hanging without reporting an error when I try to facet  
or scan a has\_child query. I suspect this may be due to some parent  
objects which are missing. If this is indeed the issue would it be  
possible to either report an error or allow the query to skip the  
missing parent objects (perhaps returning a dummy object with the  
record id it was trying to find)?

Can you post an issue with a recreation? Scanning a parent child query might be problematic, but not sure why it hangs.

Adding all the parent objects seems to fix the hanging problem. I  
will see if I can come up with a trivial recreation and post an issue.
