ca.uhn.fhir.jpa.search.elastic.IndexNamePrefixLayoutStrategy

All Implemented Interfaces:

org.hibernate.search.backend.elasticsearch.index.layout.IndexLayoutStrategy

@Service
public class IndexNamePrefixLayoutStrategy
extends Object
implements org.hibernate.search.backend.elasticsearch.index.layout.IndexLayoutStrategy

This class instructs hibernate search on how to create index names for indexed entities. In our case, we use this class to add an optional prefix to all indices which are created, which can be controlled via JpaStorageSettings.setHSearchIndexPrefix(String).
