2.1 billion documents (including deleted documents) per Lucene index, but
essentially per Solr shard as well.
But don’t even think about going that high. In fact, don't plan on going
above 100 million unless you do a proof of concept that validates that you
get acceptable query and update performance . There is no hard limit besides
that 2.1 billion Lucene limit, but... performance will vary.
