问题
I have a spring boot, Spring Data JPA (hibernate) web application and want to introduce text search feature.
I understand the following
Both hibernate search or spring-data-* can be integrated into my app
Hibernate search can work with embedded Lucene or external elastic search.
External elastic search/ solr has its own benefits, but I am ok with
embedded also to start with.
My questions
- Which library is better for easy development and maintenance.
- I see many pros and cons of solr vs elasticsearch but need Pros and Cons of Hibernate search vs spring-data-*
- I found an example on introducing Hibernate Search in an existing application. but nothing on spring-data-, how to reindex or trigger indexing of existing database data in spring-data-

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: https://github.com/snowdrop/spring-boot-hibernate-search-booster
