Source filtering with Java High Level Rest Client

[krakenbauss]

How can you perform source filtering with the Java High Level Rest Client

For example if I'm doing a reindex request, I would do something like the following to only include the fields which are relevant to me.

POST _reindex
{
    "source": {
        "index": "twitter",
        "_source": ["user", "_doc"]
    },
    "dest": {
        "index": "new_twitter"
    }
}

Is it even possible to achieve the same through the Java Client's ReindexRequest?

ReindexRequest reindexRequest = new ReindexRequest();
reindexRequest.setSourceIndices("twitter");
reindexRequest.setDestIndex("new_twitter");
// how can you set the fields to include?

Hey,

you can change the underlying search request, that is used within the reindex request

req.getSearchRequest().source().fetchSource(...)

hope this helps.

Yes, that is exactly what I needed.
