关系数据库（如 Oracle DB）的搜索引擎实现
Search Engine implementation for relational database like Oracle DB
我需要为 Oracle 等关系数据库创建一个搜索引擎。我必须借助 Elastic Search 创建一个搜索引擎。经过一周的分析，我仍然不确定；这个需求应该遵循什么样的架构呢
Spring boot-spring data-elasticsearch
Spring data-elasticsearch
Spring boot-hibernatesearch
在此之后，我浏览了这个网站，对休眠搜索有了一些想法。
http://hibernate.org/search/releases/5.9/
还是不太清楚我必须遵循哪一个来实现关系数据库的搜索引擎。有什么建议吗？
所引用的搜索引擎类似于附加的搜索组件。
如果您的问题是关于是使用 Spring-Data 还是 Hibernate Search，那么您可能想看看 my answer to this other question.

I'm obviously biased since I am a Hibernate developer, but I can at
least provide some elements focused on Hibernate Search. As to which
is "better", that's for you to judge.
The main difference is that Hibernate Search provides integration
between JPA and your index of choice (Lucene or Elasticsearch):
- Hibernate Search will automatically add/update/delete documents in your full-text index according to changes in your JPA entities (as
soon as you commit a transaction).
- Hibernate Search will allow your to build a full-text query (full-text world), and retrieve the results as managed entities (JPA
world).
As far as I understand, Spring-Data-Elasticsearch is focused on
accessing Elasticsearch and has no JPA integration whatsoever. That is
to say, you can use Spring-Data-JPA, and you can use
Spring-Data-Elasticsearch, but they won't communicate with each other.
You will have two separate models, which you will update and query
separately.
Some other elements:
- If you don't need a distributed index, Hibernate Search can run in embedded Lucene mode, without all the Elasticsearch stack. It will
probably be more lightweight.
- Hibernate Search is currently not very flexible when it comes to customizing your Elasticsearch mapping or using advanced Elasticsearch
features, because of the abstraction layer. That will change in the
future, though (Hibernate Search 6).
- A Spring-Data-HibernateSearch module is in the works, allowing to benefit from the best of both worlds. It hasn't been released yet and
is not really well documented yet, though:
