Hibernate Search and Elasticsearch demo

This repository shows how to connect from a pure Hibernate application to elasticsearch.

Scenarios

You can look at the different branches:

• pure hibernate
• direct connection to elasticsearch
• connection to elasticsearch using hibernate search

Run!

To run the project:

git checkout <00-legacy|01-elasticsearch|02-hibernatesearch>
mvn clean install

You should see something like:

[INFO] --- maven-failsafe-plugin:2.19.1:integration-test (default) @ hibernate-search-with-elasticsearch-tia ---

Running elasticsearch

When using docker, you can run the es.sh script. Basically it does:

#! /bin/sh

docker stop hsearch_es
docker rm hsearch_es
docker run -p 9200:9200 -p 9300:9300 -d --name hsearch_es elasticsearch:2.4
docker logs -f hsearch_es

When done, you can stop the docker instance:

docker stop hsearch_es
