Entity.java

@Document(indexName = "entity")
@Setting(settingPath = "/config/elasticsearch/setting/autocomplete.json")
public class Entity implements Serializable {
  
    @Column(name = "name")
    @MultiField(
            mainField = @Field(type = FieldType.String),
            otherFields = {
                    @NestedField(
                            dotSuffix = "raw",
                            type = FieldType.String,
                            store = true,
                            index = FieldIndex.not_analyzed
                    ),
                    @NestedField(
                            dotSuffix = "autocomplete",
                            type = FieldType.String,
                            indexAnalyzer = "autocomplete",
                            searchAnalyzer = "autocomplete_search"
                    )
            }
    )
    private String name;
  
}

@field and @NestedField annotations does not work with me
