How Groovy script can be invoked using java api for Elasticsearch

Question

Looking for pointers to know how Groovy script can be invoked using java api.

test.groovy

def value = dynamicValue    
return value

Want to translate following query in Java:

GET /test-index/_search
{
   "query": {
      "match_all": {}
   },
   "script_fields": {
      "checkValue": {
         "script": "test",
         "params": {
            "dynamicValue": 7
         }
      }
   }
}

I must warn, make sure your ES-cluster cannot be called from outside (I had sudden shutdown, and Chinese Chicken roosting in my ES) both from HTTP as Transport — Danielson

@Danielson : I am invoking ES to run when i have data to index using java-api & after it is done I am searching for it & in one of the case I need to filter data based on some condition that is written in groovy placed in ES directory. In this case, how ES-cluster can be called from outside ? I didn't get properly,can you please explain? — Tushar Khanna

First of, if your version is > v1.4.3 and you haven't changed script.groovy.sandbox.enabled: false to script.groovy.sandbox.enabled: true, then ignore me! Otherwise, you need to check whether you can access your cluster by your_external_ip_address:9200 (you shouldn't get a response). Try to connect as a Node to your cluster from a far-away computer, you must not be able to access, try like Client CLIENT = new TransportClient(ImmutableSettings.settingsBuilder().put("cluster.name", "your_name").build()).addTransportAddress(new InetSocketTransportAddress("external_ip", 9300));. — Danielson

Btw, this was what I was talking about elastic.co/guide/en/elasticsearch/reference/current/… — Danielson

according to the elastic.co link: If you are running a vulnerable version of Elasticsearch, you should either upgrade to at least v1.3.8 or v1.4.3, or disable dynamic Groovy scripts by adding this setting to the config/elasticsearch.yml file in all nodes in the cluster: script.groovy.sandbox.enabled: false as you said. So according to ES, you're fine... — Danielson

You can do it like this:

Map<String, Object> params = ImmutableMap.of("dynamicValue", 7);
SearchResponse response = client().prepareSearch("test-index")
        .setQuery(matchAllQuery())
        .addScriptField("checkValue", new Script("test", ScriptType.FILE, "groovy", params))
        .execute().actionGet();

You need to store your test.groovy file in the config/scripts folder on each data node and also make sure scripting is enabled in config/elasticsearch.yml with

script.inline: on
script.file: on

Thanks @Val for your quick response :) But i am wondering can it also be done using FilterBuilders.scriptFilter() which returns ScriptFilterBuilder ? Basically i want to filter my data based on some condition which will be passed as params.

Yes, you can do it as shown here, however, I'm not certain you can use scripts stored in files, only inlined ones.

@AjayTakur this is very old stuff, I believe you described your issues in this thread
