A new, experimental Elasticsearch integration was introduced in this series.
With the Elasticsearch integration, rather than indexing your entities directly by managing the Lucene resources, Hibernate Search will be sending RPCs to an Elasticsearch cluster to achieve a very similar purpose: after all it is also Lucene based, so the feature match is extremely close!
Since Hibernate Search will transparently map all the current features to this new alternative backend, you will be able to switch to a new architecture with only minimal changes in your applications. For most users the differences will be mostly in configuration details.
When using Elasticsearch, Hibernate Search will need to send RPCs over the network to run queries and index updates, but on the other hand you benefit from Microservices - style decoupling and all the nice features that Elasticsearch can provide in terms of running and managing an horizontally scalable cluster.
To know more about this integration, check out the Elasticsearch chapter in the documentation.
The QueryBuilder interface now has an additional
allowing to easily build sort definitions regardless of the underlying technology
(raw Lucene or Elasticsearch),
and without worrying about numeric field types:
QueryBuilder builder = fullTextSession.getSearchFactory() .buildQueryBuilder().forEntity(Book.class).get(); Query luceneQuery = builder.all().createQuery(); FullTextQuery query = fullTextSession.createFullTextQuery( luceneQuery, Book.class ); Sort sort = builder .sort() .byField("author").desc() // Descending order .andByField("title") // Default order (ascending) .createSort(); query.setSort(sort); List results = query.list();
The Lucene dependency was upgraded to 5.5.
Also, do not think Lucene was forgotten in this series, since there were several bug fixes and performance improvements. See the release notes for details.
async reader strategy has been added for the Lucene integration,
bringing performance boosts when you are okay with your queries being run
on an out-of-date index (how much out-of-date is configurable).
Refer to the documentation for more information.
