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。
更新内容：
HSEARCH-402: A new async reader strategy has been added for the Lucene indexing service, bringing performance boosts when you are okay with your queries being run on an out-of-date index (how much out-of-date is configurable).
HSEARCH-2260: A new VALIDATE index schema management strategy has been added for Elasticsearch, allowing you to automatically check on startup that your Hibernate Search mappings are in line with the Elasticsearch mappings.
Issues with @IndexedEmbedded in the Elasticsearch integration have be addressed: everything should now work properly, with the notable exception of @IndexedEmbedded.indexNullAs (not to be confused with @Field.indexNullAs).
HSEARCH-2235: You can now configure Hibernate Search to send requests to Elasticsearch servers in round-robin, enabling load-balancing. Failover is not supported yet, but we’ll be working on it.
HSEARCH-2360: Elasticsearch projections now use source filtering, greatly reducing the bandwidth needs when retrieving results.
We now test our Elasticsearch integration against version 2.4.2, which fixed an issue with date formats that impacted Hibernate Search. We strongly recommend to update your 2.4.x instances to the lastest available version in the 2.4.x series.
