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

Query.createWeight介绍

[英]Expert: Constructs an appropriate Weight implementation for this query.

Only implemented by primitive queries, which re-write to themselves.
[中]专家：为此查询构造适当的权重实现。
仅由原语查询实现，原语查询会重新写入自身。
