HM-SpringCloud微服務系列6.2【搜尋結果處理】

阿新 • • 發佈：2022-03-27

1 排序

搜尋的結果可以按照使用者指定的方式去處理或展示。
elasticsearch預設是根據相關度算分（_score）來排序，但是也支援自定義方式對搜尋結果排序。可以排序欄位型別有：keyword型別、數值型別、地理座標型別、日期型別等。

1.1 普通欄位排序

keyword、數值、日期型別排序的語法基本一致。

語法

GET /indexName/_search
{
  "query": {
	"match_all": {}
  },
  "sort": [
	{
	  "FIELD": "desc"  // 排序欄位、排序方式ASC、DESC
	}
  ]
}

排序條件是一個數組，也就是可以寫多個排序條件。按照宣告的順序，當第一個條件相等時，再按照第二個條件排序，以此類推

需求描述：酒店資料按照使用者評價（score)降序排序，評價相同的按照價格(price)升序排序

點選檢視程式碼

# sort排序
GET /hotel/_search
{
  "query": {
    "match_all": {}
  },
  "sort": [
    {
      "score": {
        "order": "desc"
      },
      "price": {
        "order": "asc"
      }
    }
  ]
}

# 效果同上(推薦這種order簡化寫法)
GET /hotel/_search
{
  "query": {
    "match_all": {}
  },
  "sort": [
    {
      "score": "desc",
      "price": "asc"
    }
  ]

1.2 地理座標排序

地理座標排序略有不同。

語法

GET /indexName/_search
{
  "query": {
	"match_all": {}
  },
  "sort": [
	{
	  "_geo_distance" : {
		  "FIELD" : "緯度，經度", // 文件中geo_point型別的欄位名、目標座標點
		  "order" : "asc", // 排序方式
		  "unit" : "km" // 排序的距離單位
	  }
	}
  ]
}

這個查詢的含義是：
- 指定一個座標，作為目標點
- 計算每一個文件中，指定欄位（必須是geo_point型別）的座標到目標點的距離是多少
- 根據距離排序
需求描述：實現對酒店資料按照到你的位置座標的距離升序排序
- 提示：獲取你的位置的經緯度的方式：https://lbs.amap.com/demo/jsapi-v2/example/map/click-to-get-lnglat/
- 假設我的位置是：31.034661，121.612282，尋找我周圍距離最近的酒店。

2 分頁

elasticsearch 預設情況下只返回top10的資料。而如果要查詢更多資料就需要修改分頁引數了。elasticsearch中通過修改from、size引數來控制要返回的分頁結果：
- from：從第幾個文件開始
- size：總共查詢幾個文件
類似於mysql中的limit ?, ?

2.1 基本分頁

分頁的基本語法如下：

GET /hotel/_search
{
  "query": {
    "match_all": {}
  },
  "from": 0, // 分頁開始的位置，預設為0
  "size": 5, // 期望獲取的文件總數，預設為10
  "sort": [
    {"price": "asc"}
  ]
}

2.2 深度分頁

2.2.1

現在，我要查詢990~1000的資料，查詢邏輯要這麼寫：

GET /hotel/_search
{
  "query": {
	"match_all": {}
  },
  "from": 990, // 分頁開始的位置，預設為0
  "size": 10, // 期望獲取的文件總數
  "sort": [
	{"price": "asc"}
  ]
}

這裡是查詢990開始的資料，也就是第990~第1000條資料。
不過，elasticsearch內部分頁時，必須先查詢 0~1000條，然後擷取其中的990 ~ 1000的這10條：

查詢TOP1000，如果es是單點模式，這並無太大影響。
但是elasticsearch將來一定是叢集，例如我叢集有5個節點，我要查詢TOP1000的資料，並不是每個節點查詢200條就可以了。
因為節點A的TOP200，在另一個節點可能排到10000名以外了。
因此要想獲取整個叢集的TOP1000，必須先查詢出每個節點的TOP1000，彙總結果後，重新排名，重新擷取TOP1000。

那如果我要查詢9900~10000的資料呢？是不是要先查詢TOP10000呢？那每個節點都要查詢10000條？彙總到記憶體中？
當查詢分頁深度較大時，彙總資料過多，對記憶體和CPU會產生非常大的壓力，因此elasticsearch會禁止from+ size 超過10000的請求。

2.2.2 深度分頁問題

2.2.3 深度分頁解決方案

針對深度分頁，ES提供了兩種解決方案，官方文件：

search after：分頁時需要排序，原理是從上一次的排序值開始，查詢下一頁資料。官方推薦使用的方式。
scroll：原理將排序後的文件id形成快照，儲存在記憶體。官方已經不推薦使用。

2.3 小結

分頁查詢的常見實現方案以及優缺點：

from + size：
- 優點：支援隨機翻頁
- 缺點：深度分頁問題，預設查詢上限（from + size）是10000
- 場景：百度、京東、谷歌、淘寶這樣的隨機翻頁搜尋
after search：
- 優點：沒有查詢上限（單次查詢的size不超過10000）
- 缺點：只能向後逐頁查詢，不支援隨機翻頁
- 場景：沒有隨機翻頁需求的搜尋，例如手機向下滾動翻頁
scroll：
- 優點：沒有查詢上限（單次查詢的size不超過10000）
- 缺點：會有額外記憶體消耗，並且搜尋結果是非實時的
- 場景：海量資料的獲取和遷移。從ES7.1開始不推薦，建議用 after search方案。

3 高亮

3.1 高亮原理

什麼是高亮顯示呢？
搜尋結果中吧搜尋關鍵詞突出顯示
我們在百度，京東搜尋時，關鍵字會變成紅色，比較醒目，這叫高亮顯示：
高亮顯示的實現分為兩步：
- 1）給文件中的所有關鍵字都新增一個標籤，例如<em>標籤
- 2）頁面給<em>標籤編寫CSS樣式

3.2 實現高亮

語法

GET /hotel/_search
{
  "query": {
	"match": {
	  "FIELD": "TEXT" // 查詢條件，高亮一定要使用全文檢索查詢
	}
  },
  "highlight": {
	"fields": { // 指定要高亮的欄位
	  "FIELD": {
		"pre_tags": "<em>",  // 用來標記高亮欄位的前置標籤，預設就是em標籤，可以不寫
		"post_tags": "</em>" // 用來標記高亮欄位的後置標籤
	  }
	}
  }
}

注意：
- 高亮是對關鍵字高亮，因此搜尋條件必須帶有關鍵字，而不能是範圍這樣的查詢。
- 預設情況下，高亮的欄位，必須與搜尋指定的欄位一致，否則無法高亮
- 如果要對非搜尋欄位高亮，則需要新增一個屬性：required_field_match=false
