设置数据

Person foo = new Person();

foo.setName("Foo");

foo.setId("1");

List cars = new ArrayList();

Car subaru = new Car();

subaru.setName("Subaru");

subaru.setModel("Imprezza");

cars.add(subaru);

foo.setCar(cars);

索引

IndexQuery indexQuery = new IndexQuery();

indexQuery.setId(foo.getId());

indexQuery.setObject(foo);

//creating mapping

elasticsearchTemplate.putMapping(Person.class);

//indexing document

elasticsearchTemplate.index(indexQuery);

//refresh

elasticsearchTemplate.refresh(Person.class, true);

搜索

QueryBuilder builder = nestedQuery("car", boolQuery().must(termQuery("car.name", "subaru")).must(termQuery("car.model", "imprezza")));

SearchQuery searchQuery = new NativeSearchQueryBuilder().withQuery(builder).build();

List persons = elasticsearchTemplate.queryForList(searchQuery, Person.class);
