Elasticsearch-URL查询实例解析
ES（elasticsearch）,以下简称ES
ES的查询有query、URL两种方式，而URL是比较简洁的一种，本文主要以实例探讨和总结URL的查询方式
1、语法
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''包起来，否则后面的&会被识别为“后台执行”，即&后面的内容被忽略
-s 不输出查询的时间那些东西
-g 做转义用
<REST Verb>：REST风格的语法谓词，GET/POST/PUT
<Node>:节点ip，默认使用localhost
<port>:节点端口号，默认80，ES默认使用9200
<Index>:索引名，支持通配符，power_json*
<Type>:索引类型，由于一个index只有一个type，可不输入
<ID>:操作对象的ID号，可不输入
q ：前面加&，后跟查询语句
2、常用参数
q---查询字符串
sort---排序执行。可以是fieldName或 fieldName:asc/ 的形式fieldName:desc。fieldName可以是文档中的实际字段，也可以是特殊_score名称，表示基于分数的排序。可以有几个sort参数（顺序很重要）。
from---从命中的索引开始返回。默认为0。
size---要返回的点击次数。默认为10。
_source_include---查询包含某些source字段的文档。
_source_exclude---查询不包含某些source字段的文档。
timeout---搜索超时，将搜索请求限制在指定的时间值内执行，并使用在到期时累积的点击数进行保释。默认为无超时。
default_field---默认为index.query.default_field，即未指定字段前缀时返回所有字段，索引设置为*
default_operator---默认查询运算符，未指定时默认为OR。
analyzer---用于分析查询字符串的分析器名称。
_source---设置为false禁用_source字段检索。
analyze_wildcard---是否应分析通配符和前缀查询,默认为false
status:active---where the status field contains active
---（status相当于fieldname,active相当于值----->TESTID：39232032303039,由于=被用在了前面“q=”,所以这里用“：”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:[-- TO --]---All days in
count:[ TO *]---Numbers from upwards
count:>=---Numbers from upwards

curl 'localhost:9200/power_json*/_search?pretty&analyze_wildcard&q=TESTID:10000000107326732674' //模糊查询
curl 'localhost:9200/power_json*/_search?pretty&q=VAL:<200' //比较大小
curl 'localhost:9200/power_json*/_search?pretty&_source=false' //是否显示
curl 'localhost:9200/power_json*/_search?pretty&_source_includes=TIME,VAL' //设置包含的字段
curl -g 'localhost:9200/power_json*/_search?pretty&q=(SOLAR:1%20AND%20CENTRAL:1)' //组合查询
curl -g 'localhost:9200/power_json*/_search?pretty&q=TIME:[2019-05%20TO%202019-06]' //范围查询
4、详解
4.1、查询节点
heap.percent：堆内存，1/2最大内存-1和31之间取较小的值，高的话就是ES集群负担比较重，解决：关闭一些索引（阈值差不多可以定在80左右）后会释放一部分heap.percent，但不会释放disk.percent
ram.percent：一直挺高，物理内存的使用情况，Lucene会将闲置的内存都占用做cache，如果有应用使用内存时，cache会被释放出来
cpu：一般不会很高，5以下吧，如果有很多query的话会高，如果一直高释放不掉可能查询语句有问题
node.role：【mdi】master data i查询接口（可否在节点上查询）
[zhang@node2 ~]$ curl localhost:/_cat/nodes?v
ip heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name
192.168.243.74 0.09 0.08 0.10 di - node5
192.168.243.35 0.11 0.19 0.23 mdi - node2
192.168.243.11 0.19 0.14 0.14 mdi * node1
192.168.243.51 0.07 0.09 0.13 di - node4
192.168.243.40 0.05 0.14 0.20 mdi - node3
4.2、查询节点健康状态
[zhang@node2 ~]$ curl localhost:/_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
:: zhang green - 100.0%
4.3、查询节点
disk.percent显示占用的硬盘空间
[zhang@node2 ~]$ curl 'localhost:19200/_cat/allocation?v&s=node'
shards disk.indices disk.used disk.avail disk.total disk.percent host ip node
.9tb .2tb .9tb .2tb 192.168.243.11 192.168.243.11 node1

4.12、比较大小查询
[zhang@node2 ~]$ curl 'localhost:19200/power_json*/_search?pretty&q=VAL:<200' //对于数值型和浮点型可以用比较来查
{
"took" : ,
"timed_out" : false,
"_shards" : {
"total" : ,
"successful" : ,
"skipped" : ,
"failed" :
},
"hits" : {
"total" : ,
"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" : ,"VAL" : 0.0,
"MULT" : 1.0,
"IB" : 5.0,
"IMAX" : 60.0,
"SOLAR" : ,"CT" : 1.0,
"PT" : 1.0,
"RAP_R" : 0.0,
"GLYS" : 0.0,"file" : "7326401_2018_07_23.csv"
}
},
...........
]
}
}
4.13、查询并不显示具体内容
[zhang@node2 ~]$ curl 'localhost:19200/power_json*/_search?pretty&_source=false' //只要total,不要详细内容信息。
{
"took" : ,
"timed_out" : false,
"_shards" : {
"total" : ,
"successful" : ,
"skipped" : ,
"failed" :
},
"hits" : {
"total" : ,
"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
},
..............
]
}
}
4.14、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" : ,
"timed_out" : false,
"_shards" : {
"total" : ,
"successful" : ,
"skipped" : ,
"failed" :
},
"hits" : {
"total" : ,
"max_score" : 1.0,
"hits" : [
{
"_index" : "power_json-7326401-2018.07",
"_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,
"_source" : {
"VAL" : 12309.11,
"TIME" : "2018-07-28T16:00:00"
}
},
..............
]
}
}
4.15、组合查询
[zhang@node2 ~]$ curl -g 'localhost:19200/power_json*/_search?pretty&q=(SOLAR:1%20AND%20CENTRAL:1)' //组合查询，
{
"took" : ,
"timed_out" : false,
"_shards" : {
"total" : ,
"successful" : ,
"skipped" : ,
"failed" :
},
"hits" : {
"total" : ,
"max_score" : 2.0,
"hits" : [
{
"_index" : "power_json-7326401-2018.12",
"_type" : "power_json",
"_id" : "AWf4wx0mKIIEhMjP8l5Y",
"_score" : 2.0,
"_source" : {
"TIME" : "2018-12-21T16:00:00","VAL" : 0.0,
"MULT" : 800.0,
"IB" : 1.5,
"IMAX" : 6.0,
"SOLAR" : ,"CT" : 8.0,
"PT" : 100.0,
"RAP_R" : 0.0,
"GLYS" : 0.0,"file" : "7326401_2018_12_22.csv"
}
},
..........
]
}
}
4.16、范围查询
错误示例：
[zhang@node2 ~]$ curl 'localhost:19200/power_json*/_search?pretty&q=TIME:[2019-06-19%20TO%202019-06-20]' //范围查询 TO
curl: () [globbing] error: bad range specification after pos #要加 -g
[zhang@node2 ~]$ curl -g 'localhost:19200/power_json*/_search?pretty&q=TIME:[2019-06-19%20TO%202019-06-20]' //index的日期不对，没有日
{
"took" : ,
"timed_out" : false,
"_shards" : {
"total" : ,
"successful" : ,
"skipped" : ,
"failed" :
},
"hits" : {
"total" : ,
"max_score" : null,
"hits" : [ ]
}
} [zhang@node2 ~]$ curl 'localhost:19200/_cat/indices/power_json*2019.06*'
