對索引操作的類為KbIndexProcesser
文檔主體類:Article
public class Article {
private String id;
private String topic;
private String content;
private String categoryId;
private String category;
.......
}
附件實體類:ArticleAttach
public class ArticleAttach {
private String id;
private String articleId;
private String fileName;
private byte[] fileBlob;
......
}
KbIndexProcesser 創建索引的代碼:
public class KbIndexProcesser {
private static final String INDEX_STORE_PATH = "luceneIndex";//索引存放路徑
private static final int CONTENTS_SHOW_LENGTH = 200;//文字摘要的長度
private static final int MAX_RESULT = 20;//最大的搜索結果數,沒做分頁
/**
* 創建索引
* @param article
* @param articleAttach
* @param attachOnly 隻為附附建索引嗎
* @throws LuceneException
*/
public void createIndex(Article article, ArticleAttach articleAttach, boolean attachOnly)
throws LuceneException {
IndexWriter indexWriter = null;
File indexDir = new File(INDEX_STORE_PATH);
//debug
Analyzer analyzer = new CJKAnalyzer();
long startTime = new Date().getTime();
try{
if (indexDir.exists()) {
indexWriter = new IndexWriter(indexDir, analyzer, false);
} else {
indexWriter = new IndexWriter(indexDir, analyzer, true);
}
if (attachOnly == false){
//文章主體建索引
Document document = this.createArticleIndex(article);
indexWriter.addDocument(document);
}
// 附件建索引
if (articleAttach != null){
Document attachDocument = this.createAttachIndex(article, articleAttach);
indexWriter.addDocument(attachDocument);
}
indexWriter.optimize();
indexWriter.close();
} catch(Exception ex){
ex.printStackTrace();
throw new LuceneException();
}
long endTime = new Date().getTime();
System.out.println("It takes " + (endTime - startTime)
+ " milliseconds to create index for the files in directory "
+ indexDir.getPath());
}
}
所用分詞器為CJKAnalyzer,曾使用CWordAnalyzer 分詞,但它在高亮顯示處理時會報錯,不知是何故,故棄之。
