我想在Lucene.net中对索引进行排序,如何在c#中对这个进行降序？

Question

我有从Lucene.net排序结果的代码,但我需要按降序排序搜索结果:

var sort = new Lucene.Net.Search.Sort(
    new Lucene.Net.Search.SortField("date", Lucene.Net.Search.SortField.LONG));

Answer 1

Lucene.Net.Search.Sort构造函数有一个重载来反转排序顺序:

var sort = new Lucene.Net.Search.Sort(
    new Lucene.Net.Search.SortField("date", Lucene.Net.Search.SortField.LONG),
    true);
