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

Field.isStored介绍

[英]True iff the value of the field is to be stored in the index for return with search hits. It is an error for this to be true if a field is Reader-valued.
[中]如果字段的值存储在索引中，则返回搜索命中数，则为True。如果字段为读取器值，则此为真是错误的。
