#### Using ElasticSearch as the search engine instead of the default Apache Lucene
1. Install ElasticSearch server and the phonetic plugin
* Download ElasticSearch from https://www.elastic.co/downloads/elasticsearch
* ```cd {your elasticsearch directory}```
* ```bin/plugin install analysis-phonetic```
* start ElasticSearch server: ```./bin/elasticsearch```
2. Replace configuration in web.xml
* replace the configuration class ```ca.uhn.fhir.jpa.demo.FhirServerConfig``` in web.xml by ```ca.uhn.fhir.jpa.demo.elasticsearch.FhirServerConfig```
3. Start server by runing: ```mvn jetty:run```
4. Limitations:
* Hibernate search are not compatible with all ElasticSearch version. If you are using Hibernate search: 5.6 or 5.7, the compatible ElasticSearch version is 2.0 - 2.4. If you are using Hibernate search: 5.8 or 5.9, the compatible ElasticSearch version is
2.0 - 5.6.
* Please check all the limitations in the reference documentation: https://docs.jboss.org/hibernate/search/5.7/reference/en-US/html_single/#elasticsearch-limitations before use the integration.
