Since Solr 4.1, stored fields are compressed. This probably means that in order to get a tiny field out, it must still retrieve an an entire block of compressed data and uncompress it. The information in the issue that added the compression feature says that only one compressed block is ever retrieved for a complete document. https://issues.apache.org/jira/browse/LUCENE-4226 I wonder if perhaps either Solr or Lucene is dropping all the data into one or more caches even though you only requested the ID, simply because it is already available after decompression. This is only a guess, and I hope I'm wrong. If this is indeed happening, it would defeat lazy field loading. Can someone with a better understanding comment? Thanks, Shawn
