[ElasticSearch] not_analyzed and wildcard query

24 Apr 2017 elastic

1. not_analyzed

  • contain 검색을 할거다.

2. wildcard

  • ‘*’, ‘?’로 매칭할 수 있음.
  • ‘*’ 은 SQL 에서 ‘%’ 와 비슷하다.(all characters match)
  • SQL 예시 : SELECT * FROM {TABLE_NAME} where {컬럼} like ‘%{검색할 단어}%’
  • ’?’ 는 single character match
  • 주의사항 : ‘*’, ‘?’를 첫 시작으로 사용하면 안됨.
  • 샘플
curl -XPOST http://localhost:9200/{테스트Index}/{테스트Type}/_search?pertty -d '{
"query" : {
	"wildcard" : {
		"{테스트 Field}": "*얍*"
		}
	}
}
