	},

	"aggregations": {

		"goods": {

				"field": "goods",

				"size": 10000,

				"min_doc_count": 1,

				"shard_min_doc_count": 0,

				"show_term_doc_count_error": false,

				"order": [{

					"_count": "desc"

				}, {

					"_key": "asc"

				}],

				"collect_mode": "breadth_first"

			},

			"aggregations": {

				"index": {

					"terms": {

						"field": "_index",

						"size": 10,

						"min_doc_count": 2,

						"shard_min_doc_count": 0,

						"show_term_doc_count_error": false,
