lucene.net IndexSearcher查不出来数据。大虾们指点下撒。谢谢了。

[qq624585943]

刚开始学lucene.net。不是很会。希望大虾们指导下，是不是我的查询写错了。

string strPath = @"E:\web";

IndexWriter writer = new IndexWriter(FSDirectory.GetDirectory(strPath, true), new StandardAnalyzer(), true);
Document doc1 = new Document();
doc1.Add(new Field("name", "name1", Field.Store.YES, Field.Index.NO));
doc1.Add(new Field("value", "value1", Field.Store.YES, Field.Index.NO));
Document doc2 = new Document();
doc2.Add(new Field("name", "name2", Field.Store.YES, Field.Index.NO));
doc2.Add(new Field("value", "value2", Field.Store.YES, Field.Index.NO));
writer.AddDocument(doc1);
writer.AddDocument(doc2);
writer.Optimize();
writer.Close();


IndexSearcher searcher = new IndexSearcher(strPath);
QueryParser qp = new QueryParser("name", new StandardAnalyzer());
Query query = qp.Parse("name:name1");
Hits hits = searcher.Search(query);

Response.Write(hits.Length().ToString());

查了些资料的。RAMDirectory内存中可以读取。FSDirectory就读取不出来了。不知道什么问题。公司催的紧啊。
