Hi Joel, LeafReader.getContext() is expected to return "the root IndexReaderContext <https://lucene.apache.org/core/5_2_0/core/org/apache/lucene/index/IndexReaderContext.html> for this IndexReader <https://lucene.apache.org/core/5_2_0/core/org/apache/lucene/index/IndexReader.html>'s sub-reader tree." ( https://lucene.apache.org/core/5_2_0/core/org/apache/lucene/index/LeafReader.html#getContext() ) Which means it will returns a context with ord 0 (a newly constructed, not the previous one [1]) if it is already a leaf. So I think this is expected?
