Fabio Massimo Ercoli ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate Search ( https://hibernate.atlassian.net/browse/HSEARCH?atlOrigin=eyJpIjoiMmJiNGFj... ) / Task ( https://hibernate.atlassian.net/browse/HSEARCH-3897?atlOrigin=eyJpIjoiMmJ... ) HSEARCH-3897 ( https://hibernate.atlassian.net/browse/HSEARCH-3897?atlOrigin=eyJpIjoiMmJ... ) Support explain query while changing the index name ( https://hibernate.atlassian.net/browse/HSEARCH-3897?atlOrigin=eyJpIjoiMmJ... ) Issue Type: Task Affects Versions: 6.0.0.Beta6 Assignee: Unassigned Components: backend-lucene Created: 18/Apr/2020 06:41 AM Fix Versions: 6.0.0.Beta-backlog-high-priority Priority: Major Reporter: Fabio Massimo Ercoli ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) It seems we cannot do an explain query using the Lucene extension if we change the index name, e.g: setting the name attribute of an @Index annotation. On attach I will leave a patch to reproduce the case, it targets the showcase IT module, I didn’t have the time to understand if the issue is due by the mapper or by the backend side. E.g: changing the index name from Book to book (all lowercase) the error message will be: org.hibernate.search.util.common.SearchException: HSEARCH600077: Document with id '1' does not exist in index 'book' and thus its match cannot be explained.
