1. lucene-3.5.0.jar

2. 新建目录C:\testsource，新建目录C:\testindex。

3.在C:\testsource下新建test1.txt, test2.txt，内容分别为：“商务休闲品牌男装西裤衬衫”，“潮流休闲品牌女装裙子大衣”。

4.创建索引

import java.io.BufferedReader;import java.io.File;import java.io.FileInputStream;import java.io.IOException;import java.io.InputStreamReader;import java.util.Date;import org.apache.lucene.analysis.Analyzer;import org.apache.lucene.analysis.standard.StandardAnalyzer;import org.apache.lucene.document.Document;import org.apache.lucene.document.Field;import org.apache.lucene.index.IndexWriter;import org.apache.lucene.index.IndexWriterConfig;import org.apache.lucene.index.IndexWriterConfig.OpenMode;import org.apache.lucene.store.Directory;import org.apache.lucene.store.FSDirectory;import org.apache.lucene.util.Version;/** * 给text文件建立索引 * @author liam.huang@foxmail.com */public class TextFileIndexer {		public static void main(String[] args) throws Exception{				//text文件路径		File sourceDir = new File("C:\\testsource");		File[] sourceFiles = sourceDir.listFiles();				//索引文件路径		File indexDir = new File("C:\\testindex");		Directory indexFilesDir = FSDirectory.open(indexDir);				//构建analyzer		Analyzer analyzer = new StandardAnalyzer(Version.LUCENE_35);				//配置IndexWriter		IndexWriterConfig iwConfig = new IndexWriterConfig(Version.LUCENE_35, analyzer);		iwConfig.setOpenMode(OpenMode.CREATE);				//构建IndexWriter		IndexWriter indexWriter = new IndexWriter(indexFilesDir, iwConfig);				long startTime = new Date().getTime();		for(int i=0; i

输出结果：

File C:\testsource\test1.txt正在被索引......商务休闲品牌男装西裤衬衫File C:\testsource\test2.txt正在被索引......潮流休闲品牌女装裙子大衣花费了569 毫秒把文档增加到索引里面去！索引文件地址：C:\testsource

5.关键字检索

import java.io.File;import org.apache.lucene.analysis.Analyzer;import org.apache.lucene.analysis.standard.StandardAnalyzer;import org.apache.lucene.index.IndexReader;import org.apache.lucene.queryParser.QueryParser;import org.apache.lucene.search.IndexSearcher;import org.apache.lucene.search.Query;import org.apache.lucene.search.ScoreDoc;import org.apache.lucene.search.TopDocs;import org.apache.lucene.store.FSDirectory;import org.apache.lucene.util.Version;/** * 关键字检索 * @author liam.huang@foxmail.com */public class TextQuery {		public static void main(String[] args) throws Exception{				String queryString = "休闲 装";		//索引文件路径		String indexDir = "C:\\testindex";		IndexReader indexReader = IndexReader.open(FSDirectory.open(new File(indexDir)));		IndexSearcher indexSearcher = new IndexSearcher(indexReader);				Query query = null;		Analyzer analyzer = new StandardAnalyzer(Version.LUCENE_35);		QueryParser queryParser = new QueryParser(Version.LUCENE_35, "body", analyzer);		queryParser.setDefaultOperator(QueryParser.AND_OPERATOR);		query = queryParser.parse(queryString);				ScoreDoc[] hits = null;		if(indexSearcher!=null){			//返回最多为10条记录 			TopDocs results = indexSearcher.search(query, 10);			hits = results.scoreDocs;			if(hits.length>0){				System.out.println("找到:" + hits.length + " 个结果！");			}else{				System.out.println("没有找到");			}			indexSearcher.close();		}			}}
