solr에서 여러 엔터티를 선언하는 동안 오류가 발생했습니다.

Question

방금 ​​solr을 배우기 시작했습니다. 나는 아파치 톰캣 서버와 solr 3.5를 설치했다. 하나의 엔티티에 대한 오라클 데이터베이스에서 데이터를 검색하기위한 solr을 성공적으로 구성했습니다. 내가 구성이 같은 내 데이터-config.xml 파일을 데이터-config.xml에 두 개의 엔티티를 추가하고 SOLR의 schema.xml.I에 필드를 추가하고 때 나는

solr은 두 번째 엔티티의 필드를 읽을 수 없습니다. 누구나이 문제에서 나를 도울 수 있습니까 ..? data-config.xml 또는 schema.xml 또는 두 파일을 구성하는 동안 실수를 저에게 말하십시오.

Answer 1

스택 트레이스에서 Plan 문서 중 하나가 필수 plans_applied 필드의 값이 누락 된 것처럼 보입니다 , 당신이 알아야 할 첫 번째 사항은 데이터가 Solr에서 정규화되지 않아야한다는 것입니다. 그것은 인덱스에 들어가기 전에 평평 해지기로되어 있습니다.

따라서 두 테이블을 별도의 엔티티로 인덱싱하는 대신 이러한 두 테이블 간의 조인 (쿼리 대신 data-config.xml에서 직접)을 생성하여 각 결과 (조인) 테이블 행이 Solr 문서.

그런 식으로 단일 프로젝트에 대한 모든 데이터를 얻으려는 경우 모든 문서가 단일 문서에 저장되므로 이러한 유스 케이스의 조인이 필요하지 않습니다.

Solr에서 관계 및 제약 사항이 아닌 중복성을 포용해야합니다.

의미가 있습니까?
