Solr and Lucene do not handle that caching. Systems external to Solr (like the OS, or HDFS) handle the caching. The cache effectiveness will be a combination of the cache size, overall data size, and the data access patterns of the application. I do not know enough to tell you how the cursorMark feature and the streaming API work when they access the index data. I would imagine them to be pretty similar, but cannot be sure about that.
