Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate Search ( https://hibernate.atlassian.net/browse/HSEARCH?atlOrigin=eyJpIjoiMGRhYWM0... ) / Task ( https://hibernate.atlassian.net/browse/HSEARCH-3909?atlOrigin=eyJpIjoiMGR... ) HSEARCH-3909 ( https://hibernate.atlassian.net/browse/HSEARCH-3909?atlOrigin=eyJpIjoiMGR... ) Restore support for looking up the capabilities of each field in the metamodel ( https://hibernate.atlassian.net/browse/HSEARCH-3909?atlOrigin=eyJpIjoiMGR... ) Issue Type: Task Assignee: Unassigned Components: backend-elasticsearch, backend-lucene, engine Created: 04/May/2020 02:36 AM Fix Versions: 6.0.0-Bonus-backlog Priority: Major Reporter: Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) I.e. we need a way to know which predicates/sorts/projections/etc. are available for a given field. This will make it possible to implement something similar to jpamodelgen, where classes are generated at compile-time to represent the index metamodel and can be used in the Search DSL (something that's been requested before ( https://discourse.hibernate.org/t/hsearch-metamodel/3915 ) ). There was (limited) support for that in Search 5, through org.hibernate.search.metadata.FieldSettingsDescriptor#getType , org.hibernate.search.metadata.FieldSettingsDescriptor#getIndex , org.hibernate.search.metadata.FieldSettingsDescriptor#getStore. This ticket is a follow-up on HSEARCH-3589 ( https://hibernate.atlassian.net/browse/HSEARCH-3589 ) In Progress.
