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

BooleanQuery.iterator介绍

[英]Returns an iterator on the clauses in this query. It implements the Iterable interface to make it possible to do:

for (BooleanClause clause : booleanQuery) {}

[中]返回此查询中子句的迭代器。它实现了Iterable接口，从而可以执行以下操作：

for (BooleanClause clause : booleanQuery) {}
