Hi, Is there an automatic way to map a search result like [http://www.elasticsearch.org/guide/reference/api/search/fields.html](http://www.elasticsearch.org/guide/reference/api/search/fields.html) to the correspondig object type? Let's say that I have stored a "Person" object with firstName, latName and age and I make a query for firstName and age fields. How can I map _automatically_ the response to the Person?

I suppose that you are talking about Java Beans, aren't you? You have to do it yourself using the same _tools_ you used when indexing. For example, if you use Jackson use it when deserializing. Have a look here: [https://github.com/elasticsearchfr/hands-on/blob/answers/src/test/java/org/elasticsearchfr/handson/ex2/SearchTest.java#L268](https://github.com/elasticsearchfr/hands-on/blob/answers/src/test/java/org/elasticsearchfr/handson/ex2/SearchTest.java#L268) ## HTH David 😉 Twitter : @dadoonet / @elasticsearchfr / @scrutmydocs Le 10 mars 2013 à 22:01, Mihai Cazacu [cazacugmihai@gmail.com](mailto:cazacugmihai@gmail.com) a écrit : Hi, Is there an automatic way to map a search result like [http://www.elasticsearch.org/guide/reference/api/search/fields.html](http://www.elasticsearch.org/guide/reference/api/search/fields.html) to the correspondig object type?

Yes, I already did this. It's simple when you have access to "getSourceAsString". But how about mapping a query response like this: GetResponse response = client.prepareGet(index, type, id).setFields("title","name","postDate").execute().actionGet(); Thanks, Mihai -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Did you look at the link I gave you? > SearchResponse sr = node.client().prepareSearch().setQuery(qb).execute().actionGet(); ObjectMapper mapper = new ObjectMapper(); // create once, reuse for (SearchHit hit : sr.getHits()) { Beer beer = mapper.readValue(hit.getSourceAsString().getBytes(), Beer.class); } It should do what you are expecting?

Yes, I looked at that link but it is not related to my question. I have a SearchResponse as a response for a query that request only some fields from the object (I mentioned in my initial post the link to the query type [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/api/search/fields.html)): SearchRequestBuilder requestBuilder = client.prepareSearch.... > requestBuilder.addFields("field1", "field5.subField2", "field7") Now, I want to build my objects from the response. SearchHits hitsInfo = response.getHits() > SearchHit hits = hitsInfo.hits() > for (SearchHit hit : hits) { ``` // here, hit.getSourceAsString() returns null Map fields = hit.fields() ``` > ``` > MyFullObject obj = decodeMyFullObject(hit) > > ``` > > } So, my MyFullObject must be populated with that fields (that represent a part of all MyFullObject fields) returned by the response.

Ok. I see now. Thanks for the clarification. I'm afraid you have to build yourself your entity using getters/setters for all individual fields or to create a new JSON with your fields and use Jackson. One more comment, you can also ask for field \_source in requestBuilder.add(). -- David 😉 Twitter : @dadoonet / @elasticsearchfr / @scrutmydocs Le 12 mars 2013 à 08:18, Mihai Cazacu [cazacugmihai@gmail.com](mailto:cazacugmihai@gmail.com) a écrit : Yes, I looked at that link but it is not related to my question.

Thanks, David. I resorted to this solution but I thought that there is an easy way for that mapping.
