ElasticSearch聚合存储桶始终只显示10个结果

我对负载数据使用了elasticsearch聚合,当传递offset count时,响应结果显示正确,但是术语聚合结果/bucket始终只显示10个结果。

Map<String, BucketStats> hourAggregations = new HashMap<>();
    SearchResponse getResponse = client.prepareSearch( ElasticSearchConstants.INDEX ).setTypes( ElasticSearchConstants.TABLE)
            .addAggregation( AggregationBuilders.terms( "name")
                    .field( "empId" )
                    .subAggregation( AggregationBuilders.stats( "stats" )
            .setQuery( query )
            .setFrom( 0 )
            .setSize( ( offset + 1 ) * 10 )
            .execute().actionGet();

    Terms terms = getResponse.getAggregations().get("name");
    for ( Terms.Bucket bucket : terms.getBuckets() )
    {
    //buckets showing only 10 results
    }
