Lucene.Net 2.3.2

Lucnee:全文信息检索工具包

(1)下载svn客户端 url【http://tortoisesvn.net/downloads。】中文补丁包,安装,重启电脑。

(2)新建文件夹 D:\Src\Lucene\Lucene.Net，右键SVN检出，url框输入url【https://svn.apache.org/repos/asf/incubator/lucene.net/trunk/】，下载Lucene。

(3)打开项目文件Lucene.net-2.3.2. 缺少引用ICSharpCode.SharpZipLib？？？？？？？？？？

(4) 下载url:【http://www.icsharpcode.net/OpenSource/SharpZipLib/】dll包。再次添加引用,编译项目。ok。

(5)创建一个C#控制台程序。对Lucene.Net的操作分为建立索引，和搜索两部分???

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    //索引
    using Lucene.Net.Index;
    using Lucene.Net.Store;

    using Lucene.Net.Documents;

    using Lucene.Net.Analysis.Standard;
    //搜索
    using Lucene.Net.Search;
    using Lucene.Net.QueryParsers;

    class Program
    {
        static void Main(string[] args)
        {
            //建立索引
            CreateIndex();
            //搜索索引
            SearchIndex();
        }

        #region Search Index

        private static void SearchIndex()
        {
            Analyzer analyzer = new StandardAnalyzer();
            IndexSearcher searcher = new IndexSearcher("IndexDirectory");

            MultiFieldQueryParser parse = new MultiFieldQueryParser(new string[] { "title", "content" }, analyzer);
            Query query = parse.Parse("SQL");
            Hits hits = searcher.Search(query);
            for (int i = 0; i < hits.Length(); i++) {
                Document doc = hits.Doc(i);
                Console.WriteLine(string.Format("title:{0} content:{1}", doc.Get("title"), doc.Get("content")));
            }
            searcher.Close();
            Console.Read();
        }

        #endregion

        #region Create Index

        private static void CreateIndex()
        {
            Analyzer analyzer = new StandardAnalyzer();
            IndexWriter writer = new IndexWriter("IndexDirectory", analyzer, true);
            AddDocument(writer, "SQL 2008 发布_Title", "SQL 2008 新特性_content");
            AddDocument(writer, "Asp.net mvc_Title", "mvc 框架发布_content");
            writer.Optimize();
            writer.Close();
        }

        private static void AddDocument(IndexWriter writer, string title, string content)
        {
            Document document = new Document();
            document.Add(new Field("title", title, Field.Store.YES, Field.Index.TOKENIZED));
            document.Add(new Field("content", content, Field.Store.YES, Field.Index.TOKENIZED));
            writer.AddDocument(document);
        }

        #endregion
    }
}

运行：title :xx.. content: xx………(略)

D:\Src\Lucene\Demo\Demo1\ConsoleApplication1\bin\Debug\IndexDirectory

存放着3个文件 _1.cfs  、segments.gen 、segmaents_6 不知道干嘛的。
