Hibernate Search 全文检索工具
Hibernate Search是在apache Lucene的基础上建立的主要用于Hibernate的持久化模型的全文检索工具。像Lucene这样的检索引擎能够给我们的项目在进行检索的时候带来 非常高的效率，但是它们在基本对象的检索时会有一些问题，比如不能实现检索内容跟实体的转换，Hibernate Search正是在这样的情况下发展起来的，基于对象的检索引擎，能够很方便的将检索出来的内容转换为具体的实体对象。此外Hibernate Search能够根据需要进行同步或异步的索引更新。
Hibernate Search 5.5.0.CR1 发布了，改进内容包括：
** Bug
* [HSEARCH-1956] - Exception on sorting on NumericField and indexNullAs
* [HSEARCH-1960] - TypeMetadata and QueryValidator fail to recognize an Id being encoded as Numeric
* [HSEARCH-1968] - NPE on Faceting queries which represent and empty result
* [HSEARCH-1973] - ConnectedMultiFieldsTermQueryBuilder must unwrap a NullEncodingTwoWayFieldBridge before checking for NumericFieldBridge
* [HSEARCH-1981] - QueryBuilder should not tokenize the null-token when searching for null
** New Feature
* [HSEARCH-1491] - Support queries on Numeric fields by value "null"
* [HSEARCH-1947] - Create custom bridges for Java 8 Date and Time classes
* [HSEARCH-1984] - Provide means of configuring fields to sort on
** Task
* [HSEARCH-1946] - Make sure the performance tests do cleanup the filesystem indexes
* [HSEARCH-1954] - Require JDK 8 for building
* [HSEARCH-1959] - Add JavaDoc to ExtendedSearchIntegrator#getIndexedTypesPolymorphic()
* [HSEARCH-1962] - Verify if the indexwriter.max_thread_states configuration property still applies
* [HSEARCH-1963] - Make sure we point users to an Infinispan version for integration which supports Lucene 5
* [HSEARCH-1965] - Remove dead code from DocumentExtractorImpl
* [HSEARCH-1972] - Upgrade to Hibernate ORM 5.0.0.Final
* [HSEARCH-1978] - Fix example in projection documentation
* [HSEARCH-1979] - Upgrade to WildFly 10.0.0.Beta2
