我有根据查询分组获取 mimetypeGroup 的感觉查询-
GET /_all/explore/_search
{
"size": 0,
"aggs": {
"mimeTypeGroup": {
"terms": {
"field": "mimeTypeGroup"
}
}
}
}
我如何在 java 代码中执行这个查询。我已经在我的 java 代码中尝试过这个来获得结果。我需要的结果在下面添加-
client.prepareSearch().setIndices(getIndexNames()).addAggregation(AggregationBuilders.cardinality("mimeTypeGroup").field("mimeTypeGroup")).setTypes("explore").execute().actionGet(ES_TIMEOUT_MS)
但它给了我 json 之类的 -
