Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate Search ( https://hibernate.atlassian.net/browse/HSEARCH?atlOrigin=eyJpIjoiYjcyMTlm... ) / New Feature ( https://hibernate.atlassian.net/browse/HSEARCH-4294?atlOrigin=eyJpIjoiYjc... ) HSEARCH-4294 ( https://hibernate.atlassian.net/browse/HSEARCH-4294?atlOrigin=eyJpIjoiYjc... ) Targeting of "implicit" fields in the Search DSL ( https://hibernate.atlassian.net/browse/HSEARCH-4294?atlOrigin=eyJpIjoiYjc... ) Change By: Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Elasticsearch creates some implicit fields when indexing, and so does Hibernate Search: * {{_index}} (the name of the index) * {{_entity_type}} (the name of the indexed entity type) * etc. It would be nice to be able to refer to these fields in the Search DSL, even though they weren't declared anywhere, e.g.: {code :java } AggregationKey<Map<String, Long>> countsByEntityKey = AggregationKey.of( "countsByEntity" ); SerachResult<MyEntity> result = searchSession.search(MyEntity.class).extension(ElasticsearchExtension.get()) .where(...) .aggregation(countsByEntityKey, f -> f.terms() .field( "_entity_type", String.class )) .fetch( 20 ); {code} Note we do NOT want the same for the internal Lucene fields: those are private and should not be relied on by application developers.
