Add full-text search to a Spring Boot 4 application with Hibernate Search 8.4 and Lucene: map the entity, register the analyzer as a Spring bean, index existing rows on ApplicationReadyEvent, and expose a paged, sorted REST search endpoint tested with MockMvc.
In Lucene, ByteBuffersDirectory is for pure in-memory access for demos, and MMapDirectory uses memory-mapped files stored in the filesystem.
Hibernate Search adds full-text search to Hibernate entities. Map fields with @FullTextField, @KeywordField and @GenericField, let the index follow every commit, rebuild it with the MassIndexer, and search with match, phrase, bool, range, sorting, paging and highlighting on Hibernate Search 8.4 and Lucene.
