This is currently submitted as a patch in LUCENE-6422 (placed in our lucene package until its committed to lucene 5.x). It removes unnecessary transient memory usage for QuadPrefixTree and, for 1.6.0+ shape indexes adds a new compact bit encoded representation for each quadcell. This is the heart of numerous false positive matches, OOM exceptions, and all around poor shape indexing performance. The compact bit representation will also allows for encoding 3D shapes in future enhancements.
