Lucene 검색(애플릿)(Lucene3.5)

/*오늘 검색한 애플릿을 봤는데 요약은 다음과 같다.
Lucene에서 검색을 수행하려면 다음과 같이 하십시오.
1...Derectory 만들기
2...IndexReader 작성
3...IndexReader를 기반으로 IndexSearcher 작성
4...검색을 위한 Query 만들기
5...검색어에서 TopDocs 객체 검색 및 반환
6...TopDocs에서 ScoreDoc 객체 가져오기
7....검색어와 ScoreDoc 대상에서 구체적인 Document 대상을 얻습니다
8...Document 객체에서 원하는 값 가져오기
9...reader 닫기
