Issues

Support runtime polymorphism on associations (instead of defining the indexed properties based on the returned type)

Make it possible to configure an alternative IndexDeletionPolicy

Allow for the creation of a index backup

@IndexedEmbedded.includePaths should allow to pick paths that were excluded from the embedded entity

Use Jandex instead of hibernate-commons-annotations for annotation discovery

Offer ability to define template based directories for sharding

Minimize file descriptor usage by coupling the IndexReader lifecycle to Merger activity

Composite bridges

Implement updateable numeric fields

Indexing and querying of primitive types

API to declare free-form entity properties

Grouping the search result by index field (field collapsing)

Expose indexing queue length and other backend performance metrics

Log all properties and their values at startup time

Query based approach for reindexing resolution

Support for on-demand/lazy initialization of backend resources

Support for parallel searchers

Indexed resolution (truncation) for date/time types

Add a hidden "origin" field to be able to select documents created in a same batch

Restore support for statistics

Restore support for MoreLikeThisQueries

Type-safe field references

Predicates on bridge-registered object fields

Projections on bridge-registered object fields

Add options for match predicates targeting multiple fields

Predicates with reduced scope (narrowed target type) in predicate DSL

Improve reactive support in the backend

Near-zero-downtime mass indexing when the schema did not change

Implement multi-index operations such as purge or delete-by-query as a single Elasticsearch call

Combine the results of a database query and a search query

Replace the searchable/sortable/projectable flags for fields with a single array of feature flags

Provide integrations to real-world spatial libraries

Extracting and indexing map entries

Filters based exclusively on mapper metadata for @IndexedEmbedded

Object fields that are both nested and flattened (ES's include_in_parent)

Tracing indexing requests and search queries

Regexps on normalized fields are normalized on Elasticsearch

SPI for "hot" restart that allows compatible schema changes with Lucene but doesn't interrupt search/indexing availability

Loading of non-root entities in search queries

Inner hits in search queries

Annotation processor or Maven/Gradle plugins for static metamodel generation

Better Kotlin integration for the Search DSL

See if `java.util.stream.Collector` can be used instead of `ProjectionCollector`

Hibernate ORM Sort on Hibernate Search queries

Optimize indexedEmbedded use case with id retrieval only

Optimizing Document update/recreate process by reading values back from the Document

Facet Use Cases

Hibernate Search Referential Cache

Offer ability to filter out @IndexedEmbedded instances based on their state
