### 인덱스 생성

 

index명: indexnews

 

type명: typenews

 

뉴스기사의 title과 summary 는 nori로 형태소 분석을 하고 link, 매체명은 형태소 분석없이 그대로 인덱싱.

 

만약 아래 코드를 그대로 입력하면 에러가 나며 설치되지 않는다. 사용자사전(userdic_ko.txt)을 생성한 후 실행한다. 에러날때 위치가 나타나므로 참고해도 되고, 통상 config 아래 생성하면 된다.

 

 

index 생성 

 

curl -XPUT -H 'Content-Type: application/json'   http://localhost:9200/test1

 

index 삭제 

 

curl -XDELETE -H 'Content-Type: application/json'   http://localhost:9200/test1

 

 

별도의 json 파일 생성 후 index 생성 

 

curl -s -XPUT -H 'Content-Type: application/json' http://localhost:9200/test1/ -d @ 1.json
