以下例子采用 Lucene.NET 1.9 版本，可取去 Lucene.NET 下载。

1. 基本应用

using System;
using System.Collections.Generic;
using System.Text;
using Lucene.NET;
using Lucene.NET.Analysis;
using Lucene.NET.Analysis.Standard;
using Lucene.NET.Documents;
using Lucene.NET.Index;
using Lucene.NET.QueryParsers;
using Lucene.NET.Search;
using Lucene.NET.Store;
using Lucene.NET.Util;

namespace ConsoleApplication1.Lucene
{
   public class LuceNETest
   {
     private const string FieldName = "name";
     private const string FieldValue = "value";

     private Directory directory = new RAMDirectory();
     private Analyzer analyzer = new StandardAnalyzer();

     public LuceNETest()
     {
     }

     private void Index()
     {
       IndexWriter writer = new IndexWriter(directory, analyzer, true);
       writer.maxFieldLength = 1000;
      
       for (int i = 1; i <= 100; i++)
       {
         Document document = new Document();

         document.Add(new Field(FieldName, "name" + i, Field.Store.YES, Field.Index.UN_TOKENIZED));
         document.Add(new Field(FieldValue, "Hello, World!", Field.Store.YES, Field.Index.TOKENIZED));

         writer.AddDocument(document);
       }

       writer.Optimize();
       writer.Close();
     }

     private void Search()
     {
       Query query = QueryParser.Parse("name*", FieldName, analyzer);

       IndexSearcher searcher = new IndexSearcher(directory);

       Hits hits = searcher.Search(query);
      
       Console.WriteLine("符合条件记录:{0}; 索引库记录总数:{1}", hits.Length(), searcher.Reader.NumDocs());
       for (int i = 0; i < hits.Length(); i++)
       {
         int docId = hits.Id(i);
         string name = hits.Doc(i).Get(FieldName);
         string value = hits.Doc(i).Get(FieldValue);
         float score = hits.Score(i);

         Console.WriteLine("{0}: DocId:{1}; Name:{2}; Value:{3}; Score:{4}",
           i + 1, docId, name, value, score);
       }

       searcher.Close();
     }
   }
}
