In theory, yes. A single core/index is limited by the Lucene limit of 2.14 billion documents (document number is non-negative and represented as a signed Java "int"), but you can use shards to get a multiple of that. You can put 50 to 250 million (maybe more, depending on the data) documents in a single shard. You also will want replication of each shard for query capacity.
