本文整理了Java中org.apache.lucene.index.Term.text()方法的一些代码示例，展示了Term.text()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。Term.text()方法的具体详情如下：
包路径：org.apache.lucene.index.Term
类名称：Term
方法名：text

Term.text介绍

[英]Returns the text of this term. In the case of words, this is simply the text of the word. In the case of dates and other types, this is an encoding of the object as a string.
[中]返回此术语的文本。就单词而言，这只是单词的文本。对于日期和其他类型，这是将对象编码为字符串。
