ES（elasticsearch）,如下簡稱ESnode

ES的查詢有query、URL兩種方式，而URL是比較簡潔的一種，本文主要以實例探討和總結URL的查詢方式json

一、語法

curl [ -s][ -g][ -X<REST Verb>][ -H 'Content-Type: application/json'] '<Node>:<Port>/<Index>[/Type][/ID]/_search?pretty&q=<search string>'
　　注意要用''包起來，不然後面的&會被識別爲「後臺執行」，即&後面的內容被忽略
　　-s 不輸出查詢的時間那些東西
　　-g 作轉義用　　
　　<REST Verb>：REST風格的語法謂詞，GET/POST/PUT
　　<Node>:節點ip，默認使用localhost
　　<port>:節點端口號，默認80，ES默認使用9200
　　<Index>:索引名，支持通配符，power_json*
　　<Type>:索引類型，因爲一個index只有一個type，可不輸入
　　<ID>:操做對象的ID號，可不輸入
　　q  ：前面加&，後跟查詢語句

二、經常使用參數

q---查詢字符串
sort---排序執行。能夠是fieldName或 fieldName:asc/ 的形式fieldName:desc。fieldName能夠是文檔中的實際字段，也能夠是特殊_score名稱，表示基於分數的排序。能夠有幾個sort參數（順序很重要）。
from---從命中的索引開始返回。默認爲0。
size---要返回的點擊次數。默認爲10。
_source_include---查詢包含某些source字段的文檔。
_source_exclude---查詢不包含某些source字段的文檔。
timeout---搜索超時，將搜索請求限制在指定的時間值內執行，並使用在到期時累積的點擊數進行保釋。默認爲無超時。
default_field---默認爲index.query.default_field，即未指定字段前綴時返回全部字段，索引設置爲*
default_operator---默認查詢運算符，未指定時默認爲OR。
analyzer---用於分析查詢字符串的分析器名稱。
_source---設置爲false禁用_source字段檢索。
analyze_wildcard---是否應分析通配符和前綴查詢,默認爲false
status:active---where the status field contains active
　　　　　　　 ---（status至關於fieldname,active至關於值----->TESTID：39232032303039,因爲=被用在了前面「q=」,因此這裏用「：」代替了「=」）
title:(quick OR brown)---where the title field contains quick or brown. If you omit the OR operator the default operator will be used
author:"John Smith"---where the author field contains the exact phrase "john smith"
_exists_:title---where the field title has any non-null value
date:[2012-01-01 TO 2012-12-31]---All days in 2012
count:[10 TO *]---Numbers from 10 upwards
count:>=10---Numbers from 10 upwards

三、總覽

curl localhost:9200/_cat/nodes?v        //查看node狀態
curl localhost:9200/_cat/health?v        //查看集羣健康情況curl 'localhost:9200/_cat/indices?v&s=index'　　　 //s=sort排序　　　　
curl 'localhost:9200/_cat/indices/power_json*?v&s=index'　　//只查power_json
curl 'localhost:9200/_cat/allocation?v&s=node'　　//獲取集羣的節點列表
curl 'localhost:9200/power_json*?pretty'　　 //pretty，美觀
curl 'localhost:9200/power_json*/_search?pretty&q=_exists_:MULT'     //是否存在
curl 'localhost:9200/power_json*/_search?pretty&q=TESTID:10000000107326732674'   //查指定的字段值
curl 'localhost:9200/power_json*/_search?pretty&q=TESTID:10000000107326732674&size=3' //查指定的字段值，並只顯示3個
curl 'localhost:9200/power_json*/_search?pretty&q=TESTID:10000000107326732674&from=2&size=3' //從第3個開始只顯示3個，即3/4/5
curl 'localhost:9200/power_json*/_search?pretty&q=TESTID:10000000107326732674&sort=TIME:desc' //按時間排序，desc降序，默認爲升序
curl 'localhost:9200/power_json*/_search?pretty&analyze_wildcard&q=TESTID:10000000107326732674'　　 //模糊查詢
curl 'localhost:9200/power_json*/_search?pretty&q=VAL:<200'　　//比較大小
curl 'localhost:9200/power_json*/_search?pretty&_source=false'　　//是否顯示
curl 'localhost:9200/power_json*/_search?pretty&_source_includes=TIME,VAL'　　//設置包含的字段
curl -g 'localhost:9200/power_json*/_search?pretty&q=(SOLAR:1%20AND%20CENTRAL:1)'　　//組合查詢
curl -g 'localhost:9200/power_json*/_search?pretty&q=TIME:[2019-05%20TO%202019-06]'　//範圍查詢

四、詳解

4.一、查詢節點

heap.percent：堆內存，1/2最大內存-1和31之間取較小的值，高的話就是ES集羣負擔比較重，解決：關閉一些索引（閾值差很少能夠定在80左右）後會釋放一部分heap.percent，但不會釋放disk.percent
ram.percent：一直挺高，物理內存的使用狀況，Lucene會將閒置的內存都佔用作cache，若是有應用使用內存時，cache會被釋放出來
cpu：通常不會很高，5如下吧，若是有不少query的話會高，若是一直高釋放不掉可能查詢語句有問題
node.role：【mdi】master data i查詢接口（能否在節點上查詢）數組

[zhang@node2 ~]$ curl localhost:19200/_cat/nodes?v
ip            heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name
192.168.243.74           50          98   0    0.09    0.08     0.10 di        -      node5

192.168.243.11           57          99   1    0.19    0.14     0.14 mdi       *      node1
192.168.243.51           65          95   0    0.07    0.09     0.13 di        -      node4
192.168.243.40           50          95   0    0.05    0.14     0.20 mdi       -      node3

4.二、查詢節點健康狀態

[zhang@node2 ~]$ curl localhost:19200/_cat/health?v
epoch      timestamp cluster status node.total node.data shards  pri relo init unassign pending_tasks max_task_wait_time active_shards_percent
1561104338 16:05:38  zhang green           5         5   3074 157326    0    0        0             0                  -                100.0%

4.三、查詢節點

[zhang@node2 ~]$ curl 'localhost:19200/power_json*/_search?pretty&q=TESTID:10000000107326732674&sort=TIME:desc'    //根據TIME排序（sort），desc降序，默認是升序
{
  "took" : 526,
  "timed_out" : false,
  "_shards" : {
    "total" : 416,
    "successful" : 416,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : 442,
    "max_score" : null,
    "hits" : [
      {
        "_index" : "power_json-7326414-2019.06",
        "_type" : "power_json",
        "_id" : "AWt1FAobp__ZtGsu1rDf",
        "_score" : null,

        },
        "sort" : [
          1560355200000
        ]
      },
      {
        "_index" : "power_json-7326414-2019.06",
        "_type" : "power_json",
        "_id" : "AWtvtXvfp__ZtGsu1SUE",

        },
        "sort" : [
          1560268800000
        ]
      },
    ]
  }
}

4.十一、模糊查詢

[zhang@node2 ~]$ curl 'localhost:19200/power_json*/_search?pretty&analyze_wildcard&q=TESTID:10000000107326732674'    //模糊查詢
{
  "took" : 38,
  "timed_out" : false,
  "_shards" : {
    "total" : 416,
    "successful" : 416,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : 442,
    "max_score" : 15.078416,
    "hits" : [
      {
        "_index" : "power_json-7326414-2019.03",
        "_type" : "power_json",
        "_id" : "AWl1vKjnZsBwX43irtmd",
        "_score" : 15.078416,
        "_source" : {
          "TIME" : "2019-03-04T16:00:00","VAL" : 2287.85,
          "MULT" : 1.0,
          "IB" : 5.0,
          "IMAX" : 60.0,
          "SOLAR" : 0,"CT" : 1.0,

          "GLYS" : 0.0,"file" : "7326414_2019_03_12.csv"
        }
      },
...........
    ]
  }
}

4.十二、比較大小查詢

[zhang@node2 ~]$ curl 'localhost:19200/power_json*/_search?pretty&q=VAL:<200'        //對於數值型和浮點型能夠用比較來查
{
  "took" : 12636,
  "timed_out" : false,
  "_shards" : {
    "total" : 416,
    "successful" : 416,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : 1811138155,
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "power_json-7326401-2018.07",
        "_type" : "power_json",
        "_id" : "AWfbqLLxKIIEhMjPv280",
        "_score" : 1.0,
        "_source" : {
          "TIME" : "2018-07-22T16:00:00","HNAME" : "",
          "CENTRAL" : 1,"VAL" : 0.0,
          "MULT" : 1.0,
          "IB" : 5.0,
          "IMAX" : 60.0,
          "SOLAR" : 0,"CT" : 1.0,
          "PT" : 1.0,
          "RAP_R" : 0.0,
          "GLYS" : 0.0,"file" : "7326401_2018_07_23.csv"
        }
      },
...........
    ]
  }
}

4.1三、查詢並不顯示具體內容

[zhang@node2 ~]$ curl 'localhost:19200/power_json*/_search?pretty&_source=false'    //只要total,不要詳細內容信息。
{
  "took" : 2933,
  "timed_out" : false,
  "_shards" : {
    "total" : 416,
    "successful" : 416,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : 1024729047326,
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "power_json-7326401-2018.07",
        "_type" : "power_json",
        "_id" : "AWfbqLLxKIIEhMjPv28Q",
        "_score" : 1.0
      },
      {
        "_index" : "power_json-7326401-2018.07",
        "_type" : "power_json",
        "_id" : "AWfbqLJXKIIEhMjPv0Rd",
        "_score" : 1.0
      },
..............
    ]
  }
}

4.1四、包含指定字段

[zhang@node2 ~]$ curl 'localhost:19200/power_json*/_search?pretty&_source_includes=TIME,VAL'    //包含TIME和VAL字段的
{
  "took" : 2894,
  "timed_out" : false,
  "_shards" : {
    "total" : 416,
    "successful" : 416,

        "_type" : "power_json",
        "_id" : "AWfbqLLxKIIEhMjPv28Q",
        "_score" : 1.0,
        "_source" : {
          "VAL" : 773260.69,
          "TIME" : "2018-07-22T16:00:00"
        }
      },
      {
        "_index" : "power_json-7326401-2018.07",
        "_type" : "power_json",
        "_id" : "AWfbqLJXKIIEhMjPv0Rd",
        "_score" : 1.0,

          "VAL" : 12309.11,
          "TIME" : "2018-07-28T16:00:00"
        }
      },
..............
    ]
  }
}

4.1五、組合查詢

[zhang@node2 ~]$ curl -g 'localhost:19200/power_json*/_search?pretty&q=(SOLAR:1%20AND%20CENTRAL:1)'    //組合查詢，
