lucene.net-按int排序

在对api做了一些研究和探索之后,我终于找到了一些非弃用的api(截至v2.9和v3.0),它们允许您按日期订购:

// Find all docs whose .Text contains "hello", ordered by .CreationDate.
var query = new QueryParser(Lucene.Net.Util.Version.LUCENE_29, "Text", new StandardAnalyzer()).Parse("hello");
var indexDirectory = FSDirectory.Open(new DirectoryInfo("c:\\foo"));
var searcher = new IndexSearcher(indexDirectory, true);
try
{
   var sort = new Sort(new SortField("CreationDate", SortField.LONG));
   var filter =  new QueryWrapperFilter(query);
   var results = searcher.Search(query, , 1000, sort);
   foreach (var hit in results.scoreDocs)
   {
       Document document = searcher.Doc(hit.doc);
       Console.WriteLine("\tFound match: {0}", document.Get("Text"));
   }
}
finally
{
   searcher.Close();
}

注意,我正在用长比较对创建日期进行排序。这是因为我将创建日期存储为datetime.now.ticks,它是一个system.int64,或者是c_中的long。
