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

Query.getBoost介绍

[英]Gets the boost for this clause.
[中]获得此子句的提升。
