> What is the use of the LiveIndexWriterConfig.createdVersionMajor It's very expert. It's necessary if you have multiple workers creating indices that you then want to merge together using `IndexWriter#addIndexes`. `addIndexes` requires that all indices have the same major version, so if you are doing a rolling upgrade on your workers to a new Lucene major, this helps ensure that all indices are created in a way that they can be merged eventually. -- This is an automated message from the Apache Git Service.
