solr 검색 색인 검색에서 쉼표로 구분 된 값을 GROUP_CANCAT을 사용하여 생성했습니다.

Question

cakephp에서 solr 검색을 통합하려고합니다. 모든 것이 잘 작동하지만 mysql 쿼리에 GROUP_CONCATE를 추가하면 내 solr 검색을 인덱싱 할 수 없습니다. 내 코드는 아래에 나열된 코드

나는 문제가 아래에 나열됩니다.

(SELECT GROUP_CONCAT(name separator ',') FROM tags JOIN article_tags ON tags.id = article_tags.tag_id WHERE article_tags.article_id = article.id) as tagnames, 

나는 다음이 코드를 제거 내 SOLR 지수는 아주 잘 작동하지만이를 추가하면 인덱싱 SOLR 동안 얻을 오류 경우 "인덱싱에 실패했습니다. 다시 모든 변경 사항을 압 연."

"tagnames는"새로운 필드가있는 태그 같은 쉼표로 분리 된 값으로 구성 생성 예 : 식품, 건강, 피트니스 등

그래서 난 구분 값

Answer 1

더블이 쉼표로 SOLR을 구성 할 "키워드"필드가 스키마에서 multiValued로 정의되어 있는지 확인하십시오. "Indexing Failed"는 일반적으로 그 이유를 알려주고 전체 스택 추적도 제공합니다.

다음 구현은 수행하려는 작업에 대해 더 잘 작동 할 수도 있습니다. 알림 "그룹 병합"쿼리를 완전히 제거하고이를 아래 엔티티로 추가했습니다. 조인과 필드 이름을 다시 확인하십시오. 이름 지정을 기반으로 연결 만 가정했습니다. 이렇게하면 추가 행렬을 수행하지 않습니다. 각 행마다 분할 작업
