Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate Search ( https://hibernate.atlassian.net/browse/HSEARCH?atlOrigin=eyJpIjoiMDI4MDlm... ) / Task ( https://hibernate.atlassian.net/browse/HSEARCH-3909?atlOrigin=eyJpIjoiMDI... ) HSEARCH-3909 ( https://hibernate.atlassian.net/browse/HSEARCH-3909?atlOrigin=eyJpIjoiMDI... ) Restore support for looking up the capabilities of each field in the metamodel ( https://hibernate.atlassian.net/browse/HSEARCH-3909?atlOrigin=eyJpIjoiMDI... ) Change By: 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}}. An interesting way to implement this would be through a {{hasCapability(String)}} methods, where the string is the name of a given capability: match predicate, "within circle" predicate, "field value" sort, "distance" sort, ... Names would be exposed as constants in some {{BuiltinCapabilities}} class, and more importantly **each backend could define additional constants for its extended capabilities**. This would be very similar to what is described in HSEARCH-3633 for field configuration. This ticket is a follow-up on HSEARCH-3589.
