Hi Thank you for sharing the details. 1) Is NumericRangeQuery is the only API removed in license 7 when compare with lucene 5.5.3?
2) To do re-index of the existing data with lucene 7, does it support all scenarios like closed partitions, backed up or archived data etc... Or any key areas which we need to be cautious to do re-index with lucense 7. 3) is any API or guide available to re-index existing data with lucense 7?
