Yes, joins support distributed search fine,
provided that the individual documents that are joined reside on the same shard.
For example, if you are modeling blogs and posts (one blog object as many posts)
shard1
------------------
joe!blog_info
joe!post1
shard2
------------------
mary!blog_info
mary!post1
So now you can search for post bodies and join to the main blog via
{!join from=blog_pointer to=blog_id}post_body:hello
If both mary and joe have a post with hello, they will both be found
and joined to their main blog info docs with a single distributed
search across the collection.
