[Elasticsearch] 1.0.0 릴리즈 이후... 변경된 것중 하나..

elasticsearch 1.0.0 에서 이전에 사용하던 API 의 return 값과 다른 것들이 좀 보입니다.

사용하시면서 기존 구조만 믿고 그냥 쓰시면 큰 낭패를 보실 수도 있을 듯 하내요.

아마도 _cat (http://www.elasticsearch.org/blog/introducing-cat-api/) 기능이 들어 가면서 영향을 받은 것들이 좀 되구요.

settings, add document, get document 등도 조금씩 달라진게 있습니다.

그냥 참고들 하세요.

대표적으로 많이 바뀐 API 하나 맛보기로 보여 드립니다.

아래는 제가 쓰고 있는 책의 예제로 클러스터 구성하던걸 띄워 본거라.. 좀 길게 나오내요.. 그래서 중복된 것들은 삭제 했습니다.. ^^;
