SolrException 수정 방법 : QueryElevationComponent가 스키마에 uniqueKeyField가 있어야합니까?

Question

바람둥이에 내장 된 solr을 설정 중입니다. 바람둥이에서 아무런 문제없이 실행되는 예제를 얻을 수 있습니다. 그런 다음 schema.xml을 매우 단순하게 변경하려고 시도하고 오류가 발생합니다.

당신의 도움이 많이 감사합니다 :

이이 내가 탈 시작 오류 내의 schema.xml

<?xml version="1.0" encoding="UTF-8" ?> 
<schema name="minimal" version="1.1"> 
<types> 
<fieldType name="string" class="solr.StrField"/> 
</types> 
<fields> 
<dynamicField name="*" type="string" indexed="true" stored="true"/> 
</fields> 
</schema> 

입니다.

Answer 1

나는 대답은 당신이 제공하는 스택 추적에 생각 :

Caused by: org.apache.solr.common.SolrException: QueryElevationComponent requires the schema to have a uniqueKeyField. 

당신이 UniqueKeyField 예를 들어

정의가없는 공급 한 예제 스키마 :

<uniqueKey>[Put name of field here]</uniqueKey> 

그러나 스키마에서 고정 필드를 정의하지 않으므로 먼저 스키마를 추가해야합니다.
