lucene使用方式

自己写了个小例子

package com.lucene.test;

import java.io.IOException;

import org.apache.lucene.index.CorruptIndexException;

import org.apache.lucene.index.IndexWriter.MaxFieldLength;
import org.apache.lucene.queryParser.ParseException;

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.store.LockObtainFailedException;

public class IndexWriterTest {
	
	public static void main(String[] args) {
		try {

			doc.add(field);
			writer.addDocument(doc);
			
			doc = new Document();
			field = new Field("descript", "描述内容", Store.YES, Field.Index.ANALYZED, Field.TermVector.NO);
			doc.add(field);
			writer.addDocument(doc);
			
			writer.optimize();

			TopDocs docs = search.search(query, 10);
			System.out.println("找到记录共"+docs.totalHits+"条。");
			ScoreDoc[] d = docs.scoreDocs;

				int id = s.doc;
