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:[2012-01-01 TO 2012-12-31]---All days in 2012 count:[10 TO *]---Numbers from 10 upwards count:>=10---Numbers from 10 upwards

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: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 192.168.243.35 39 90 0 0.11 0.19 0.23 mdi - node2 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
4.2、查询节点健康状态
[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%
4.3、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 615 1.9tb 9.2tb 8.9tb 18.2tb 51 192.168.243.11 192.168.243.11 node1 615 2.3tb 8.7tb 9.4tb 18.2tb 47 192.168.243.35 192.168.243.35 node2 614 2.2tb 7.6tb 10.5tb 18.2tb 42 192.168.243.40 192.168.243.40 node3 615 2.2tb 7.5tb 10.6tb 18.2tb 41 192.168.243.51 192.168.243.51 node4 615 2.1tb 7.1tb 11tb 18.2tb 39 192.168.243.74 192.168.243.74 node5

4.10、查询并按指定字段排序
[zhang@node2 ~]$ curl 'localhost:19200/power_json*/_search?pretty&q=TESTID:10000000107326732674&sort=TIME:desc' //根据TIME排序（sort），desc降序，默认是升序 { "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, "_source" : { "TIME" : "2019-06-12T16:00:00","VAL" : 2469.8, "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" : "7326414_2019_06_20.csv" }, "sort" : [ 1560355200000 ] }, { "_index" : "power_json-7326414-2019.06", "_type" : "power_json", "_id" : "AWtvtXvfp__ZtGsu1SUE", "_score" : null, "_source" : {"VAL" : 2468.26, "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" : "7326414_2019_06_19.csv" }, "sort" : [ 1560268800000 ] }, ] } }

[zhang@node2 ~]$ curl 'localhost:19200/power_json*/_search?pretty&analyze_wildcard&q=TESTID:10000000107326732674' //模糊查询 { "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, "PT" : 1.0, "RAP_R" : 0.0, "GLYS" : 0.0,"file" : "7326414_2019_03_12.csv" } }, ........... ] } }
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" : 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" } }, ........... ] } }
4.13、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" : 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 }, .............. ] } }
4.14、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" : 2894, "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, "_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" : 4078, "timed_out" : false, "_shards" : { "total" : 416, "successful" : 416, "skipped" : 0, "failed" : 0 }, "hits" : { "total" : 5732636, "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" : 1,"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
