Hibernate Search 5.2.0.Beta1 发布

Hibernate Search 5.2.0.Beta1 发布了，该版本最值得关注的改进就是支持多租户。多租户这个概率来源于 Hibernate ORM，但 Hibernate Search 之前不允许你使用，因为它不会在全文本查询中应用相同的隔离。现在我们实现了这个特性，使用非常简单，请看这里.

其他方面的改进包括：

** Bug
* [HSEARCH-1684] – ResultTransformer ignores transformList on tuples
* [HSEARCH-1793] – CriteriaObjectInitializer causes too many object loads in cross hierarchy queries
* [HSEARCH-1804] – Boost on IndexedEmbedded properties
* [HSEARCH-1811] – Wildcard with multiple fields
* [HSEARCH-1824] – Hot-restarting a mutable SearchFactory has it “forget” the previously defined FilterDef and Analyzers
* [HSEARCH-1825] – NullEncodingTwoWayFieldBridge doesn’t set the null marker when used as a FieldBridge
* [HSEARCH-1836] – Avoid NPE in NullEncodingTwoWayFieldBridge for non existing fields

** Improvement
* [HSEARCH-655] – Implements the FuturTask.cancel function in the MassIndexer
* [HSEARCH-1356] – Refactor WorkVisitor to match more the expectations on a Visitor pattern
* [HSEARCH-1762] – Improve javadocs of builtin bridges
* [HSEARCH-1831] – Correcting various typos in the documentation
* [HSEARCH-1850] – Avoid extending Startable and Stoppable interfaces as part of a Service contract

** New Feature

* [HSEARCH-1792] – Support multi-tenancy
* [HSEARCH-1837] – Allow Integrators to customize default directory providers for shortcuts
