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

Sort.<init>介绍

[英]Sorts by computed relevance. This is the same sort criteria as calling IndexSearcher#search(Query,int)without a sort criteria, only with slightly more overhead.
[中]按计算相关性排序。这与在没有排序条件的情况下调用IndexSearcher#search（Query，int）的排序条件相同，只是开销稍大。

代码示例

public TopDocs   search(Query query, int maxResults) throws IOException
{
  Sort sort = new Sort(new SortField(FieldNames.DATE, SortField.LONG, true));
  return searcher.search(query, maxResults, sort);
}
