 joins aren't supported in distributed search. Any time you have more than
 one shard in SolrCloud, you are, by definition, doing distributed search.

It is supported, but there is a limitation:  You can use joins, but
those joins will each be calculated locally per-shard based on common
terms within the same shard.

And you can ensure that certain sets of related documents appear on
the same shard with the new document routing feature:

 Hi,

 I'm running some join query, let's say it looks as follows: {!join
 from=some_id to=another_id}(a_id:55 AND some_type_id:3). When I run it on
 single instance of SOLR I got the correct result, but when I'm running it
 on
 the sharded system (2 shards with replica for each shard (total index
 counts
 ~300K entries)) I got partial result.

 Is there any issue with supporting join queries on sharded system or may be
 there is some configuration tweak, that I'm missing?


 Thanlks.
