'''일래스틱서치'''(Elasticsearch)는 [[루씬]] 기반의 [[검색 엔진 (컴퓨팅)|검색 엔진]]이다. [[HTTP]] 웹 인터페이스와 스키마에서 자유로운 [[JSON]] 문서와 함께 분산 [[멀티테넌시|멀티테넌트]] 지원 전문 검색 엔진을 제공한다. 일래스틱서치는 [[자바 (프로그래밍 언어)|자바]]로 개발되어 있으며 [[아파치 라이선스]] 조항에 의거하여 [[오픈 소스 소프트웨어|오픈 소스]]로 출시되어 있다. 공식 클라이언트들은 [[자바 (프로그래밍 언어)|자바]], [[닷넷 프레임워크|닷넷]]([[C 샤프|C#]]), [[PHP]], [[파이썬]], [[아파치 그루비|그루비]] 등 수많은 언어로 이용이 가능하다.<ref name="offizsite">{{웹 인용 |url=http://www.elasticsearch.org/ |title=Official Website |publisher=Elasticsearch.org |date= |accessdate=2014-02-04 |보존url=https://web.archive.org/web/20150310014128/http://www.elasticsearch.org/ |보존날짜=2015-03-10 |url-status=dead }}</ref> 일래스틱서치는 가장 대중적인 엔터프라이즈 검색 엔진으로 그 뒤를 루씬 기반의 [[Apache Solr]]가 잇는다.<ref>{{웹 인용

일래스틱서치는 로그스태시(Logstash)라는 이름의 데이터 수집 및 로그 파싱 엔진, 그리고 [[키바나]](Kibana)라는 이름의 분석 및 시각화 플랫폼과 함께 개발되어 있다. 이 3개의 제품들은 연동 솔루션으로 사용할 목적으로 설계되어 있으며 이를 "일래스틱 스택"(Elastic Stack, 과거 이름: ELK 스택)으로 부른다.

== 개요 ==
일래스틱서치는 모든 종류의 문서를 검색하는데 사용할 수 있다. 가변 검색 및 [[실시간 검색|실시간에 가까운 검색]]을 제공하며 [[멀티테넌시]]를 지원한다.<ref name="offizsite"/> 일래스틱서치는 분산 방식이므로 인덱스를 여러 [[샤드]]로 나눌 수 있으며 각 샤드는 0개 이상의 복제물(replica)을 가지고 있을 수 있다. 각 노드는 하나 이상의 샤드를 관리하며 작업을 올바른 샤드로 할당시켜 주는 조율자 역할을 한다. 리밸런싱 및 라우팅은 자동으로 수행된다.<ref name="offizsite"/> 연관 데이터는 종종 동일한 인덱스에 저장되며 이는 하나 이상의 프라이머리 샤드와 0개 이상의 복제물(replica) 샤드로 이루어진다. 인덱스가 만들어지면 프라이머리 샤드의 수는 변경할 수 없다.<ref>{{웹 인용|title=How to monitor Elasticsearch performance|url=https://www.datadoghq.com/blog/monitor-elasticsearch-performance-metrics/|확인날짜=2017-11-03|보존url=https://web.archive.org/web/20181218010528/https://www.datadoghq.com/blog/monitor-elasticsearch-performance-metrics/|보존날짜=2018-12-18|url-status=dead}}</ref>

일래스틱서치는 [[루씬]]을 사용하며 JSON과 [[자바 API]]를 통해 모든 기능을 최대한 활용한다. [[다면 검색|다면]](facetting) 및 침투(precolating)을 지원하므로<ref>{{웹 인용 |url=http://www.elasticsearch.org/guide/reference/api/percolate/ |title=percolate at elasticsearch.org reference |publisher=Elasticsearch.org |date= |accessdate=2014-02-04 |보존url=https://web.archive.org/web/20131002171546/http://www.elasticsearch.org/guide/reference/api/percolate/ |보존날짜=2013-10-02 |url-status=dead }}</ref> 새로운 문서들이 등록된 쿼리와 일치할 경우 통보하는데 유용할 수 있다.

그 밖의 기능으로 "게이트웨이"가 있으며 장기간의 인덱스 지속성을 관리한다.<ref name="gateway">{{웹 인용 | url=http://www.elasticsearch.org/guide/reference/modules/gateway/ | title=elasticsearch Guide: Gateway | publisher=elasticsearch | accessdate=April 19, 2013 | 보존url=https://web.archive.org/web/20131001084745/http://www.elasticsearch.org/guide/reference/modules/gateway/ | 보존날짜=2013-10-01 | url-status=dead }}</ref> 이를테면 인덱스는 서버 충돌 시에 게이트웨이로부터 복구할 수 있다. 일래스틱서치는 실시간 [[GET 요청]]을 지원하므로 [[NoSQL]] 데이터스토어의 역할에 적합하지만<ref name="jetslidedatabase">{{웹 인용 |url=http://karussell.wordpress.com/2011/07/13/jetslide-uses-elasticsearch-as-database/ |title=Elasticsearch as database |publisher=Karussell.wordpress.com |date= |accessdate=2014-02-04 |보존url=https://web.archive.org/web/20180821114157/https://karussell.wordpress.com/2011/07/13/jetslide-uses-elasticsearch-as-database/ |보존날짜=2018-08-21 |url-status=dead }}</ref> [[분산 트랜잭션]] 면에서는 부족하다.<ref name="transactions">{{웹 인용 |url=http://elasticsearch-users.115913.n3.nabble.com/Distributed-transaction-support-td951313.html |title=No transaction support |publisher=Elasticsearch-users.115913.n3.nabble.com |date=2010-07-08 |accessdate=2014-02-04 |보존url=https://web.archive.org/web/20181006111808/http://elasticsearch-users.115913.n3.nabble.com/Distributed-transaction-support-td951313.html |보존날짜=2018-10-06 |url-status=dead }}</ref>
