1、屬性說明和介紹

執行命令：

GET /test_index/test_type/_search?timeout=1s

運行后的結果如下：

{"took": 4,"timed_out": false,"_shards": {"total": 3,"successful": 3,"failed": 0},"hits": {"total": 11,"max_score": 1,"hits": [{"_index": "test_index","_type": "test_type","_id": "5","_score": 1,"_source": {"test_field": "test3"}},{"_index": "test_index","_type": "test_type","_id": "6","_score": 1,"_source": {"test_field": "test6"}},{"_index": "test_index","_type": "test_type","_id": "7","_score": 1,"_source": {"test_field": "test7"}},{"_index": "test_index","_type": "test_type","_id": "2","_score": 1,"_source": {"test_field": "test2"}},{"_index": "test_index","_type": "test_type","_id": "4","_score": 1,"_source": {"test_field": "test4"}},{"_index": "test_index","_type": "test_type","_id": "AWPE334kH290KcMbohDu","_score": 1,"_source": {"test_content": "my test2"}},{"_index": "test_index","_type": "test_type","_id": "AWPE4LcyH290KcMbohDx","_score": 1,"_source": {"test_content": "my test2"}},{"_index": "test_index","_type": "test_type","_id": "AWPE4ARFH290KcMbohDv","_score": 1,"_source": {"test_content": "my test2"}},{"_index": "test_index","_type": "test_type","_id": "AWPE4JVHH290KcMbohDw","_score": 1,"_source": {"test_content": "my test2"}},{"_index": "test_index","_type": "test_type","_id": "3","_score": 1,"_source": {"test_field": "test3"}}]} }

屬性介紹：
took:整個搜索花費了多少毫秒

hits.total:本次搜索，返回幾條結果
hits.max_score:本次搜索的所有結果中，最大的相關度分數是多少，每一條document對于search的相關度，越相關，_score分數越大，排位越靠前
hits.hits:默認查詢前10條數據，完整數據，_score降序排序。
**shards：**shards fail的條件（primary和replica全部掛掉），不影響其他shard。默認情況下來說，一個搜索請求，會打到一個index的所有primary shard上去，當然了，每個primary shard都可能會有一個或多個replic shard，所以請求也可以到primary shard的其中一個replica shard上去。

2、timeout圖解介紹

timeout:默認無timeout，，latency平衡completeness，手動指定timeout,timeout查詢執行機制
timeout的單位可以是：毫秒，秒，分。
例：

timeout=10ms，timeout=1s，timeout=1mGET /test_index/test_type/_search?timeout=1ms
