我正在使用 Lucene.Net 版本 2.3.2.1。当我调用 index() 方法时，它将索引 C:\Index 中的文档。但是当我调用 SearchLucene() 方法时，什么都没有出现。
这是我的 index() 和 SearchLucene() 方法：
public void Index(string strHash, string filePath, string encryptedPath, string password, string fileName)
{
string indexFileLocation = @"C:\Index";
Lucene.Net.Store.Directory dir =
Lucene.Net.Store.FSDirectory.GetDirectory(indexFileLocation, false);
//create an analyzer to process the text
Lucene.Net.Analysis.Analyzer analyzer = new
Lucene.Net.Analysis.Standard.StandardAnalyzer();
//create the index writer with the directory and analyzer defined.
Lucene.Net.Index.IndexWriter indexWriter = new
Lucene.Net.Index.IndexWriter(dir, analyzer);/*true to create a new index*/
//create a document, add in a single field
Lucene.Net.Documents.Document doc = new Lucene.Net.Documents.Document();
doc.Add(new Field("keywordHash", strHash, Field.Store.YES, Field.Index.TOKENIZED));
doc.Add(new Field("keywordPath", filePath, Field.Store.YES, Field.Index.NO));
doc.Add(new Field("keywordEncPath", encryptedPath, Field.Store.YES, Field.Index.TOKENIZED));
doc.Add(new Field("keywordPassword", password, Field.Store.YES, Field.Index.TOKENIZED));
//doc.Add(new Field("keywordEncryptedFile", encryptedFile, Field.Store.YES, Field.Index.ANALYZED));
doc.Add(new Field("keywordFileName", fileName, Field.Store.YES, Field.Index.NO));
//write the document to the index
indexWriter.AddDocument(doc);
//optimize and close the writer
indexWriter.Optimize();
indexWriter.Close();
}
public void LuceneSearch()
{
HashAlg hashAlg = new HashAlg();
string keywordLower = tbSearchEnc.Text.ToLower();
string keywordHash;
if (rbMD5Search.Checked == true)
{
keywordHash = hashAlg.GenerateHashMD5(keywordLower);
}
else
{
keywordHash = hashAlg.GenerateHashSHA1(keywordLower);
}
string indexFileLocation = @"C:\Index";
//Lucene.Net.Store.Directory dir = Lucene.Net.Store.FSDirectory.GetDirectory(indexFileLocation, false);
//Lucene.Net.Analysis.Analyzer analyzer = new Lucene.Net.Analysis.Standard.StandardAnalyzer();
Lucene.Net.Search.IndexSearcher searcher = new Lucene.Net.Search.IndexSearcher(indexFileLocation);
//create an index searcher that will perform the search
//Lucene.Net.Search.IndexSearcher searcher = new Lucene.Net.Search.IndexSearcher(dir);
//build a query object
//Query query = new TermQuery(new Term("keywordHash", keywordHash));
Lucene.Net.Index.Term searchTerm = new Lucene.Net.Index.Term("keywordHash", keywordHash);
Lucene.Net.Search.Query query = new Lucene.Net.Search.TermQuery(searchTerm);
//execute the query
Lucene.Net.Search.Hits hits = searcher.Search(query);
int result = hits.Length();
//iterate over the results.
for (int i = 0; i < result; i++)
{
Document doc = hits.Doc(i);
string hashValue = doc.Get("keywordHash");
Console.WriteLine(hashValue);
string path = doc.Get("keywordPath");
Console.WriteLine(path);
string encPath = doc.Get("keywordEncPath");
Console.WriteLine(encPath);
string fileName = doc.Get("keywordFileName");
Console.WriteLine(fileName);
listBoxSearch.Items.Add(encPath);
Console.WriteLine(hashValue + " " + path + " " + encPath + " " + fileName);
}
}
