I have two questions about the function "pickNext()" in RTree.java.The first is when (newNode.entryCount < maxNodeEntries / 2) why choose node n to add the entry.The second is why choose the smaller area of tectangle to add the entry? Would you mind give me a reply? my email:liuguanli1205@qq.com

Works out of the box. A simple test with 100 million random queries on an index containing 15.000 rectangles took about 20sec. Great!
