Enum Version

  • All Implemented Interfaces:
    Serializable, Comparable<Version>
    public enum Version
extends Enum<Version>
    Use by certain classes to match version compatibility across releases of Lucene.

    WARNING: When changing the version parameter that you supply to components in Lucene, do not simply change the version at search-time, but instead also adjust your indexing code to match, and re-index.

        WARNING: if you use this setting, and then upgrade to a newer release of Lucene, sizable changes may happen. If backwards compatibility is important then you should instead explicitly specify an actual version.

        If you use this constant then you may need to re-index all of your documents when upgrading Lucene, as the way text is indexed may have changed. Additionally, you may need to re-test your entire application to ensure it behaves as expected, as some defaults may have changed and may break functionality in your application.
