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

Query.setBoost介绍

[英]Sets the boost for this query clause to b.
[中]将此查询子句的boost设置为[$0$]。
