2GB for 27 million docs seems a little bit small even WITHOUT facets. You need to increase the heap. If you're hitting OOME doing facets on a field with such low cardinality, then I think that means you're probably running *VERY* close to your heap memory capacity. Because Java does not function well when memory is extremely tight, you'll likely find that increasing the heap will make Solr run faster in general, as well as eliminating the OOME. As Erick mentioned, turning on docValues, if the field you're faceting on supports it, will reduce the amount of heap memory required. But even with that, 2GB may simply not be enough. Thanks, Shawn
