Start with the attached NestedSpanNearTest.java or NestedSpanNearTest_20160902.patch to reproduce the nested SpanNearQuery case, then trace the relevant span-query implementation in the Lucene source. Confirm which repeating-group query fails and add a regression test showing the expected match; the issue provides no repository file path or named test command.
