    今天继续学习ES 在Windows 下的使用，主要是通过curl 命令行来操作ES：
    备注：说明一下ES 的版本为6.8.8.

    1.查看ES的相关信息

     1 C:Users	dcengineer>curl http://127.0.0.1:9200/?pretty
 2 {
 3 "name" : "node-1",
 4 "cluster_name" : "myes",
 5 "cluster_uuid" : "jImvcOwnQbilYTD8JLNtFA",
 6 "version" : {
 7 "number" : "6.8.8",
 8 "build_flavor" : "default",
 9 "build_type" : "zip",
10 "build_hash" : "2f4c224",
11 "build_date" : "2020-03-18T23:22:18.622755Z",
12 "build_snapshot" : false,
13 "lucene_version" : "7.7.2",
14 "minimum_wire_compatibility_version" : "5.6.0",
15 "minimum_index_compatibility_version" : "5.0.0"
16 },
17 "tagline" : "You Know, for Search"
18 }

    2.创建一个索引

    1 C:Users	dcengineer>curl -XPUT http://127.0.0.1:9200/index_01
2 {"acknowledged":true,"shards_acknowledged":true,"index":"index_01"}

    3.创建一个索引，并初始化一个文档

    1 C:Users	dcengineer>curl -XPUT -H "content-Type:application/json" "http://127.0.0.1:9200/testindex/student/1" -d"{"name":"tony","age":25,"score":99}"
2 {"_index":"testindex","_type":"student","_id":"1","_version":1,"result":"created","_shards":{"total":2,"successful":1,"failed":0},"_seq_no":0,"_primary_term":1}
3  
4 C:Users	dcengineer>curl -XPUT -H "content-Type:application/json" "http://127.0.0.1:9200/testindex/student/2" -d"{"name":"tony","age":33,"score":99}"
5 {"_index":"testindex","_type":"student","_id":"2","_version":1,"result":"created","_shards":{"total":2,"successful":1,"failed":0},"_seq_no":0,"_primary_term":1}

    4.更新指定的id=2的索引内容

    1 C:Users	dcengineer>curl -XPUT -H "content-Type:application/json" "http://127.0.0.1:9200/testindex/student/2" -d"{"name":"tony","age":32,"score":98}"
2 {"_index":"testindex","_type":"student","_id":"2","_version":2,"result":"updated","_shards":{"total":2,"successful":1,"failed":0},"_seq_no":1,"_primary_term":1}

    5.删除指定索引下的数据

    1 C:Users	dcengineer>curl -XDELETE -H "content-Type:application/json" "http://127.0.0.1:9200/testindex/student/2"
2 {"_index":"testindex","_type":"student","_id":"2","_version":3,"result":"deleted","_shards":{"total":2,"successful":1,"failed":0},"_seq_no":2,"_primary_term":1}

    6.删除指定的索引

    1 C:Users	dcengineer>curl -XDELETE -H "content-Type:application/json" "http://127.0.0.1:9200/test0823"
2 {"acknowledged":true}

    7.获取指定索引下id=2 的数据信息

    1 C:Users	dcengineer>curl -XGET -H "content-Type:application/json" "http://127.0.0.1:9200/testindex/student/2"
2 {"_index":"testindex","_type":"student","_id":"2","_version":1,"_seq_no":3,"_primary_term":1,"found":true,"_source":{"name":"tony","age":32,"score":98}}

    格式化后输出：

     1 C:Users	dcengineer>curl -XGET -H "content-Type:application/json" "http://127.0.0.1:9200/testindex/student/2?pretty"
 2 {
 3 "_index" : "testindex",
 4 "_type" : "student",
 5 "_id" : "2",
 6 "_version" : 1,
 7 "_seq_no" : 3,
 8 "_primary_term" : 1,
 9 "found" : true,
10 "_source" : {
11 "name" : "tony",
12 "age" : 32,
13 "score" : 98
14 }
15 }

    8.查询指定索引下的所有数据

     1 C:Users	dcengineer>curl -XGET -H "content-Type:application/json" "http://127.0.0.1:9200/testindex/_search?pretty"
 2 {
 3 "took" : 1,
 4 "timed_out" : false,
 5 "_shards" : {
 6 "total" : 5,
 7 "successful" : 5,
 8 "skipped" : 0,
 9 "failed" : 0
10 },
11 "hits" : {
12 "total" : 2,
13 "max_score" : 1.0,
14 "hits" : [
15 {
16 "_index" : "testindex",
17 "_type" : "student",
18 "_id" : "2",
19 "_score" : 1.0,
20 "_source" : {
21 "name" : "tony",
22 "age" : 32,
23 "score" : 98
24 }
25 },
26 {
27 "_index" : "testindex",
28 "_type" : "student",
29 "_id" : "1",
30 "_score" : 1.0,
31 "_source" : {
32 "name" : "tom",
33 "age" : 35,
34 "score" : 89
35 }
36 }
37 ]
38 }
39 }

    9.指定条件name=tony的数据

     1 C:Users	dcengineer>curl -XPOST -H "content-Type:application/json" "http://127.0.0.1:9200/testindex/_search?pretty" -d "{"query":{"match":{"name":"tony"}}}"
 2 {
 3 "took" : 72,
 4 "timed_out" : false,
 5 "_shards" : {
 6 "total" : 5,
 7 "successful" : 5,
 8 "skipped" : 0,
 9 "failed" : 0
10 },
11 "hits" : {
12 "total" : 1,
13 "max_score" : 0.2876821,
14 "hits" : [
15 {
16 "_index" : "testindex",
17 "_type" : "student",
18 "_id" : "2",
19 "_score" : 0.2876821,
20 "_source" : {
21 "name" : "tony",
22 "age" : 32,
23 "score" : 98
24 }
25 }
26 ]
27 }
28 }

    10.查询条件为name=tony or tom 的数据

     1 C:Users	dcengineer>curl -XPOST -H "content-Type:application/json" "http://127.0.0.1:9200/testindex/_search?pretty" -d "{"query":{"match":{"name":"tony tom"}}}"
 2 {
