Spring Data Search

Spring Search is an abstraction on the search layer aiming help developpers to use a search engine.

Spring Search provides a SearchTemplate with methods like the useful JdbcTemplate. Indeed, like the JdbcTemplate, you can add, update or extract the data directly from a QueryReponse with a QueryResponseExtractor or a DocMapper. A short list of search engines that will be integrated:

• Solr
• ElasticSearch
• Compass (deprecated in favor of ElasticSearch?)
• Exalead
• Google Custom Search
• ... any idea?

Some future features:

• Abstract common DSL
• JPA cross storage (planned)
• Transaction management
• Exception translation

Examples

// First build a search template, here for Solr:

SolrServer embeddedSolrServer = new EmbeddedSolrServer(coreContainer, "default");
SearchOperations searchOperations = new SolrTemplate(embeddedSolrServer);

// Or, in the same way, build a template using Elastic Search:

Node node = NodeBuilder.nodeBuilder().client(true).node();
Client client = node.client();
SearchOperations searchOperations = new ElasticSearchTemplate(client);

// And just do something like this:

// 1- add documents or beans

searchOperations.add(document);
searchOperations.addBeans(bean1, bean2);

// 2- retrive document using a DocMapper or via a class using @Indexed annotation

List<DummyBean> beans = searchOperations.query("id:1234", new DocMapper<DummyBean>() {
	@Override
	public DummyBean docMap(Document doc) {
		return new DummyBean((String) doc.get("id"), (Date) doc.get("last_modified"), (String) doc.get("name"));
	}
});


List<DummyBean> beans = searchOperations.query("id:1234", DummyBean.class);

// 3- have fun!
