hi, I have issues with my custom search plugin.

I have made search plugin to change scoring. It was okay till I have installed my plugin and start ES.  
But when I searched query, ES just shut down without any returning exceptions.  
In Kibana, it said {"statusCode":502,"error":"Bad Gateway","message":"read ECONNRESET"}.

I'm using 7.7 version and OS is window 10.

My plugin is based on Search plugin.

```
public class PayloadSimilarityPlugin extends Plugin implements SearchPlugin {
@Override
public List<QuerySpec<?>> getQueries() {
    return Collections.singletonList(new QuerySpec<>(PayloadQuery.NAME, PayloadQueryBuilder::new, PayloadQueryBuilder::fromXcontent));
}

```

}

I have sent a query like this. (PayloadQuery.NAME == payload\_score)

```
body = {
    "query": {
        "payload_score": {
            "query": {
                "match": {
                    "contents": "white"
                }
            }
        }
    }
}

```

How can I apply my plugin properly?  
If search plugin is not supported anymore, is there anyway to make Payload Scoring based on payload delimiter filter?
