Second reply, so I'm aiming for more detail. > 1. How many documents Solr can search at a moment?? A *single* Solr index has Lucene's limitation of slightly more than 2 billion documents. This is part of the problem solved by SolrCloud. By throwing multiple machines/shards at the problem, there is effectively no limit to the size of a SolrCloud collection. I have encountered someone who has a collection with five billion documents in it. That 2 billion document limit I mentioned, which is Java's Integer.MAX_VALUE, is the ONLY hard limit that I know of in the software, and only applies when the index is not sharded. > 2. Can Solr index the media data?? I have no idea what you meant here, but if you mean metadata, Solr most likely can handle it. If you meant actual media, like an image, I believe there is a binary field type that you can even store a full source document in, but that is not normally the way Solr is used, and I don't recommend it. > 3. What's the max size of document that Solr can index??? I don't think there is a limit. I think there are some limits on the number and size of individual terms, but not on the total size of a document. If documents get particularly large and numerous, performance might suffer, but I am not aware of any total size limitations. Thanks, Shawn
