本文整理了Java中org.apache.lucene.util.Version类的一些代码示例，展示了Version类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Version类的具体详情如下：
包路径：org.apache.lucene.util.Version
类名称：Version

Version介绍

[英]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.
[中]由某些类使用，以匹配Lucene各个版本的版本兼容性。
警告：更改Lucene中组件的版本参数时，不要在搜索时简单地更改版本，还要调整索引代码以匹配，然后重新索引。
