Hi all,
In case receiving a certain fields from a doc, I could construct query in
this way:
```
SearchRequestBuilder searchBuilder = client.prepareSearch(
```
indexName, indexType )
.setSearchType(SearchType.DFS\_QUERY\_THEN\_FETCH)
.setQuery( builder )
.addField(field)
.setFrom(0).setSize( urls.length );
I'm trying to perform a search query on an index with all the fields
returned without explicitly specifying them.
however, if I left without "addField", it returns docs without any fields.
is there a way I could retrieve this with ES java client?
Thank you.
Yuhan

You can use wildcards in the field name: .addField("\*")
Alternatively, if you have source enabled (the default), you can
extract the fields from the source: SearchHit#getSource().
Cheers,

Hi Ivan,
.addField("\*") didn't work in my case, It returns me 0 with
searchResponse.getHits().getHits()[0].getFields().values().size() ...
I tried to get the source but received null from
response.getHits().getHits()[0].getSource()
I'm wondering what I did wrong... I'm using the 0.19.4 client.
Thank you.

Hello, I am wondering if you ever solved this issue?
I am using elasticsearch-0.19.9 and the following still does not work?
SearchRequestBuilder builder = client.prepareSearch("idx1002")
.setSearchType(SearchType.DEFAULT)
.setQuery(qb1).addField("\*");
Example:
{
a:{
b: { attr: "value" }
}
}
IF I need to retrieve the field "attr" in the resulting documents, should I be adding a.b.attr via .addField("a.b.attr")?
Any help to retrieve specific field that is nested (example above) would be appreciated.
Thanks.

Have you had any luck in retrieving the fields?

Hi Vinod,
the field names of an index can be read from its mapping 🙂
[http://localhost:9200/my\_index/\_mapping?pretty=1](http://localhost:9200/my_index/_mapping?pretty=1)

Thank you Yuhan. I will used the \_mapping before, however, I was wondering
if there was some way to do this using Java API.
Thanks.
