如何使用Hibernate中的Example类在数据库中搜索相似实体

Question

i know that there are an Hibernate class called Example that we can use to get similar entities in order to do a search, but is it possible that this class permit to get entities searching in a generic way.

I explain, I build an example entity having a property called name with value = "myname", is Hibernate capable to return an entity which has property having value = "mname" ?

Answer 1

Yes that's possible but to enable text-level similarity you need a Lucene index to speed-up the query, as it would otherwise be extremely inefficient to run on a relational database.

This is provided by Hibernate Search , the extension of Hibernate to integrate with Lucene and manage the indexes transparently.
