Lucene.net简单实现

Guid g = Guid.NewGuid();
IndexWriter indexWrite = new IndexWriter(Server.MapPath("index"), new ChineseAnalyzer(), true);

string strContent = TextBox1.Text;
Document doc = new Document();
doc.Add(Field.Keyword("Id", g.ToString()));
doc.Add(Field.Text("contents",strContent));

indexWrite.AddDocument(doc);

indexWrite.Optimize();
indexWrite.Close();

using Lucene.Net.Analysis.Cn;
using Lucene.Net.QueryParsers;
using Lucene.Net.Index;
using Lucene.Net.Search;

}
else
{

}
indexSearcher.Close();
