IOException: Unknown GeoDistance ordinal [2]

[mloho]

Elasticsearch server version: {"number": "5.6.6","lucene_version": "6.6.1"}
Elasticsearch client version: 6.2.1

Plugins installed: [{ "name": "x-pack", "version": "5.6.6", "description": "Elasticsearch Expanded Pack Plugin", "classname": "org.elasticsearch.xpack.XPackPlugin", "has_native_controller": true }]

JVM version: 1.8.0_151

OS version: Linux ubuntu 4.4.0-116-generic

Description of the problem including expected versus actual behavior:
When I include a geo distance query into the should clause of my master bool query and use this query to search for results, it would produce a java.io.IOException: Unknown GeoDistance ordinal [2]
Expected: search to return with correct results. Actual: search produces an IOException.

Notes & Observations:

• The master bool query also contains other queries in its other clauses. However, the search with the same parameters works when the geo distance query is excluded.
• The search is successful if I manually copy the master bool query string and paste it into my ElasticSearch Head browser plugin (and also curl I'm assuming).

Steps to reproduce:

BoolQueryBuilder queryBuilder = QueryBuilders.boolQuery();
queryBuilder.should(
    QueryBuilders.geoDistanceQuery(term).point(origin).distance(distance)
);

client.prepareSearch(index)
        .setTypes(type)
        .setFrom(from)
        .setSize(size)
        .setQuery(queryBuilder);

Stack trace:
java.io.IOException Unknown GeoDistance ordinal [2].txt

It looks like we accidently broke backward compatibility here. Unfortunately, I cannot think of any temporary workaround besides using a client and a server with the same major version.

@mloho, thanks for the detailed report. It was fixed by #29325 and should be release in v6.3.0.
