public void createIndex() {try {File file = new File(FILE_PATH);//FILE_PATH为所要创建索引的文件的绝对地址，在地址完全可以用String来代替Document doc = new Document();IndexWriter indexWriter = new IndexWriter(INDEX_STORE_PATH,analyzer, true,MaxFieldLength.LIMITED);//INDEX_STORE_PATH索引存放的地址Field field =new Field("content",loadFileToString(file),Field.Store.NO, Field.Index.TOKENIZED);doc.add(field);field=new Field("name",file.getName(),Field.Store.YES, Field.Index.TOKENIZED);doc.add(field);field=new Field("path",file.getPath(),Field.Store.YES, Field.Index.TOKENIZED);doc.add(field);indexWriter.addDocument(doc);indexWriter.close();} catch (Exception e) {e.printStackTrace();}}

public String loadFileToString(File file) {try {BufferedReader br = new BufferedReader(new FileReader(file));StringBuffer sb = new StringBuffer();String line = br.readLine();while (line != null) {sb.append(line);line = br.readLine();}br.close();return sb.toString();} catch (IOException e) {e.printStackTrace();return null;}}
