Hi Thank you for your response. Yes moving to 8.0 will be the plan if we plan to re-index.
Before we re-index would like to know few details which will help us to decide further on that: In Lucene 6.0 migrate page(https://lucene.apache.org/core/6_0_0/MIGRATE.html) it says "*PointValues replaces NumericField*" and also says "*PointValues provides faster indexing and searching, a smaller index size, and less heap used at search time. See org.apache.lucene.index.PointValues for an introduction.*" Could we please get the *statistics* for this Point values about the performance on faster indexing and searching and also on the index size and heap used ? Thank you in Advance!
