本文介绍了一个使用Java和Lucene创建简单文本索引的例子。通过Eclipse IDE建立项目并编写代码，演示了如何利用Lucene API进行文档索引。具体包括设置索引路径、分析器的选择以及字段的添加等关键步骤。

打开eclipse，建立新工程

package bindex;
import java.io.IOException;

import org.apache.lucene.document.Document;
import org.apache.lucene.document.Field;
import org.apache.lucene.index.CorruptIndexException;
import org.apache.lucene.index.IndexWriter;
import org.apache.lucene.store.LockObtainFailedException;
import org.apache.lucene.analysis.standard.StandardAnalyzer;

public class basicindexer {

/**
* @param args
*/
public static void main(String[] args) {
  // TODO Auto-generated method stub
        String indexPath ="indexes";
      try {
  IndexWriter indexWriter = new IndexWriter(indexPath,new StandardAnalyzer());
        Document doc=new Document();
  String blogtitle="计算机软件技术与理论交流";
  String blogauthor="深未来工作室(deepfuture@qq.com)－深度创造未来";
  String blogurl="http://blog.163.com/sukerl@126/";
  Field field=new Field("title",blogtitle,Field.Store.YES,Field.Index.TOKENIZED);
  doc.add(field);
  field=new Field("author",blogtitle,Field.Store.YES,Field.Index.TOKENIZED);
  doc.add(field);
  field=new Field("url",blogurl,Field.Store.YES,Field.Index.NO);
  doc.add(field);
  indexWriter.addDocument(doc);
  indexWriter.close();
  System.out.println("OK!");
} catch (CorruptIndexException e) {
// TODO Auto-generated catch block
  e.printStackTrace();
} catch (LockObtainFailedException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
} catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
}
}

}

运行后，索引建立成功
