There are exactly two solutions to the OutOfMemoryError regarding heap space: 1) Increase the heap size. 2) Decrease the memory requirements. The default heap size that Solr 5.0 and later starts with is 512MB. This is a very small heap size. We are aware that the default is very small -- this is intentional, so that the default install is runnable on virtually any hardware. Almost all production Solr installs will require increasing the heap size. If you get a little bit of data in a Solr install and then make complex query requests, it can easily require more than 512MB of total heap. You appear to be asking about option number 2 above ... but I believe you'll be better off with option number 1. There also might be elements here of a general XY problem: http://people.apache.org/~hossman/#xyproblem Thanks, Shawn
