五、POST查詢

然後調用下方下方的請求則是一個簡單的數據查詢請求：

請求方式：POST

URL：http://192.168.1.199:9200/_search?index=megacorp&type=employee

Header：Content-Type:application/json

Body：

{
	"from": 0,
	"size": 10,
	"query": {
		"term": {
			"age": {
				"value": 30,
				"boost": 1.0
			}
		}
	},
	"sort": [{
		"birthday": {
			"order": "desc"
		}
	}]
}

請求說明：

URL：_search/?index=megacorp&type=employee 分別爲 {查詢方式}?index={索引名稱}&type={文檔名稱}  這裏的索引名稱與文檔名稱可以不填寫，但是如果不填寫則會連帶其他索引和文檔一起進行查詢，建議填寫。

Body：

{
	"from-查詢的開始位置": 0,
	"size-查詢結果數量": 10,
	"query-查詢條件，可以不填": {
		"term-查詢條件，後面會有詳細說明": {
			"age-字段名": {
				"value-值": 30
			}
		}
	},
	"sort-排序": [{
		"birthday-排序字段名": {
			"order-排序方式": "desc-倒序"
		}
	}]
}

之後會獲取到服務器的響應數據：

{
  "took": 0,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "skipped": 0,
    "failed": 0
  },
  "hits": {
    "total": 2,
    "max_score": null,
    "hits": [
      {
        "_index": "megacorp",
        "_type": "employee",
