Lucene搭建和基本使用

1.下载及安装

地址：http://lucene.apache.org/  下载src.tgz包和lucene.xxx.zip

2.查看文档构建eclipse工程

  2.1  ucene-4.6.0\docs\index.html 参考文档。点击lucene domo根据导航setting yourclasspath 。

  2.2  然后设置build path，把src包关联。打开demo

2.3   打开indexFiles，SearchFiles 的源码，参考源码自己写出例子程序。

  大概脉络是：indeFiles中构建indexWriter（需要directory和IndexWriterConfig），然后把需要相应的Filed写进document中，indexWriter.Add（doc）写进文件最后关掉。

SearchFiles的使用也是很简单。利用indexRead.search（query,num），然后遍历document。

       以下是快速使用的源码：

public classLuceneDemo {       public static voidindexFiles(String indexPath){       File indexFile = newFile(indexPath);       try {           Directory directory = FSDirectory.open(indexFile);           Analyzer analyzer = newStandardAnalyzer(Version.LUCENE_46);           AnalyzerikAnalyzer = new IKAnalyzer(true);//           IndexWriterConfig  config = newIndexWriterConfig(Version.LUCENE_46,ikAnalyzer);           IndexWriter indexWriter = newIndexWriter(directory, config);                     //FileInputStreamfis = new FileInputStream(indexFile);           Document doc = newDocument();           //Fieldfield = new StringField("path", "this is a test",Field.Store.YES);           Field field = newLongField("id", Long.valueOf(1), Field.Store.YES);           Field field2 = newTextField("title", "圣诞节日记", Field.Store.YES);           Field field3 = newTextField("content", "今天圣诞节过得很开心!因为我收到了圣诞礼物。哈哈！",Field.Store.YES);                           /*  Fieldfield = new LongField("id", Long.valueOf(2), Field.Store.YES);           Field field2 = newTextField("title", "平安夜",Field.Store.YES);           Field field3 = newTextField("content", "今天平安夜过得很开心!因为我收到了圣诞礼物。哈哈！", Field.Store.YES);           */           /*Fieldfield = new LongField("id", Long.valueOf(3), Field.Store.YES);           Field field2 = newTextField("title", "圣诞节的礼物",Field.Store.YES);           Field field3 = newTextField("content", "今天早上突然发现圣诞节礼物在我的袜子里。",Field.Store.YES);           */           doc.add(field);           doc.add(field2);           doc.add(field3);           indexWriter.addDocument(doc);           indexWriter.commit();           indexWriter.close();                 } catch(Exception e) {           e.printStackTrace();       }    }    public static voidsearchFiles(String indexPath){       File indexFile = newFile(indexPath);       try {           IndexReader indexReader =DirectoryReader.open(FSDirectory.open(indexFile));           IndexSearcher indexSearcher = newIndexSearcher(indexReader);           Analyzer analyzer = newStandardAnalyzer(Version.LUCENE_46);           //QueryParserparser = new QueryParser(Version.LUCENE_40, "path", analyzer);            TermQuery query = newTermQuery(new Term("content","圣诞礼物"));                     TopDocs topDocs = indexSearcher.search(query,10);           ScoreDoc[] scoreDocs = topDocs.scoreDocs;           int hits =topDocs.totalHits;           System.out.println(hits);           for(ScoreDocsd : scoreDocs){              int docID =sd.doc;              Document document =indexSearcher.doc(docID);                           System.out.println(document.get("id"));              System.out.println(document.get("title"));              System.out.println(document.get("content"));                        }       } catch(Exception e) {           // TODOAuto-generated catch block           e.printStackTrace();       }    }       public static voiddelIndexFiles(String indexPath){       File indexFile = newFile(indexPath);       try {           Directory directory = FSDirectory.open(indexFile);           Analyzer analyzer = newStandardAnalyzer(Version.LUCENE_46);           Analyzer ikAnalyzer = newIKAnalyzer(true);//           IndexWriterConfig  config = newIndexWriterConfig(Version.LUCENE_46,ikAnalyzer);           IndexWriter indexWriter = newIndexWriter(directory, config);                               //indexWriter.deleteAll();           indexWriter.deleteDocuments(new Term("content","圣诞礼物"));           indexWriter.commit();           indexWriter.close();                 } catch(Exception e) {           e.printStackTrace();       }    }}

 

 2.4 然后在测试程序中输入路径测试程序

@Testpublic void test1(){    String indexPath = "F:/lucene/myretrieve/luceneData";    LuceneDemo.indexFiles(indexPath);    //LuceneDemo.searchFiles(indexPath);}@Testpublic void test2(){    String indexPath = "F:/lucene/myretrieve/luceneData";    //LuceneDemo.indexFiles(indexPath);    LuceneDemo.searchFiles(indexPath);}
