Geo indexing and request

You can make request using geo_distance filter. This can be done using GeoPoint object.

First, here is a sample of an entity with a GeoPoint field (location)

@Document(indexName = "test-geo-index", type = "geo-class-point-type")
public class AuthorMarkerEntity {

    @Id
    private String id;
    private String name;

    private GeoPoint location;

    private AuthorMarkerEntity(){
    }

    public AuthorMarkerEntity(String id){
        this.id = id;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public GeoPoint getLocation() {
        return location;
    }

    public void setLocation(GeoPoint location) {
        this.location = location;
    }
}

Indexing your entity with a geo-point :

elasticsearchTemplate.createIndex(AuthorMarkerEntity.class);
elasticsearchTemplate.refresh(AuthorMarkerEntity.class, true);
elasticsearchTemplate.putMapping(AuthorMarkerEntity.class);

List<IndexQuery> indexQueries = new ArrayList<IndexQuery>();
indexQueries.add(new AuthorMarkerEntityBuilder("1").name("Franck Marchand").location(45.7806d, 3.0875d).buildIndex());
indexQueries.add(new AuthorMarkerEntityBuilder("2").name("Mohsin Husen").location(51.5171d, 0.1062d).buildIndex());
indexQueries.add(new AuthorMarkerEntityBuilder("3").name("Rizwan Idrees").location(51.5171d, 0.1062d).buildIndex());
elasticsearchTemplate.bulkIndex(indexQueries);

For your information :

• Clermont-Ferrand : 45.7806, 3.0875
• London : 51.5171, 0.1062

So, if you want to search for authors who are located within 20 kilometers around Clermont-Ferrand, here is the way to build your query :

CriteriaQuery geoLocationCriteriaQuery = new CriteriaQuery(
                new Criteria("location").within(new GeoPoint(45.7806d, 3.0875d), "20km"));
List<AuthorMarkerEntity> geoAuthorsForGeoCriteria = elasticsearchTemplate.queryForList(geoLocationCriteriaQuery, AuthorMarkerEntity.class);

This example should only return one author named "Franck Marchand".

You can even combine with other criteria (e.g. author name) :

Here, we're looking for authors located within 20 kilometers around London AND named "Mohsin Husen" :

CriteriaQuery geoLocationCriteriaQuery2 = new CriteriaQuery(
                new Criteria("name").is("Mohsin Husen").and("location").within(new GeoPoint(51.5171d, 0.1062d), "20km"));
List<AuthorMarkerEntity> geoAuthorsForGeoCriteria2 = elasticsearchTemplate.queryForList(geoLocationCriteriaQuery2, AuthorMarkerEntity.class);

This example should only return one author named "Mohsin Husen".
