http://localhost:9200/testindex/_open |
|
|
查看所有索引setting |
Get |
||
|
添加一个type |
|||
|
添加/修改一个mapping |
Put/ post |
http://localhost:9200/testindex/testtype/_mapping |
{ "testtype" : { "properties" : { "address" : { "type" : "string" }, "name" : { "type" : "string" } } }} |
|
删除mapping |
del |
http://localhost:9200/testindex/testtype |
|
添加具体的文档
|
插入文档自动生成id |
Post |
http://localhost:9200/testindex/testtype/ post每次都是创建新的 |
{ "name":"张明", "address":"中山北路" } |
|
插入文档，更新或生成 |
put |
http://localhost:9200/testindex/testtype/1 put时带具体的ID，表示修改，没有则创建 |
{ "name":"张明", "address":"中山北路" } |
|
普通查询 |
Get |
{ "name":"张明", "address":"中山北路" } |
|
|
Query查询 |
Get |
{ "name":"张明", "address":"中山北路" } |
其他操作：
|
插入文档自动生成index/type |
Post |
http://localhost:9200/testindex/testtype/ post每次都是创建新的 |
{ "name":"张明", "address":"中山北路" } |
|
插入文档自动生成index/type |
put |
http://localhost:9200/testindex/testtype/1 put时带具体的ID，表示修改，没有则创建 |
{ "name":"张明", "address":"中山北路" } |
|
同时创建index、type，不插入文档 |
Post/ put |
http://localhost:9200/testindex
后面的json格式最好不要变动，一般情况下，只要post过去的内容和查询看到的格式保持一个层次结构，都可以提交； 但是提交的格式却不一定和查询看到的一致（毕竟提交只是需要将所有的信息加上去就可以了） |
{ "settings" : { "number_of_shards" : "5", "number_of_replicas" : "1" } , "mappings" : { "testtype" : { "properties" : { "address" : { "type" : "string" }, "age" : { "type" : "string" } } } } } |
|

Post |
http://localhost:9200/testindex/_refresh |
|
|
提交索引 |
Post |
http://localhost:9200/testindex/_flush |
|
|
优化索引 |
Post |
http://localhost:9200/testindex/_optimize |
|
|
清空缓存 |
Post |
http://localhost:9200/testindex/_cache/clear |
查询操作：
|
Math_all 全集查询 |
Post |
http://172.16.20.49:9200/zuhe/zuheentity/_search http://172.16.20.49:9200/*/zuheentity/_search |
{ } |
|
Math 语义查询 |
Post |
http://172.16.20.49:9200/zuhe/zuheentity/_search http://172.16.20.49:9200/*/zuheentity/_search |
{ "query":{ "match":{ "ManagerName":"财富" } } } |
|
Math_phrase 短语查询，term查询后，进行位置匹配，得到类似like结果 |
Post |
http://172.16.20.49:9200/zuhe/zuheentity/_search http://172.16.20.49:9200/*/zuheentity/_search |
{ "query":{ "match":{ "ManagerName":"财富" } } } |
|
Term 直接用倒排索引的词项进行查询，性能好，但在应用层面，直接使用的少 |
Post |
{ "query":{ "term":{ "ManagerName":{ "value":"财", "boost":10 } } } } |
|
|
Wildcard 在term查询的基础上，增加通配符功能 |
Post |
{ "query":{ "wildcard":{ "ManagerName":{ "value":"?*" , "boost":10 } } } } |
|
|
Terms 最低匹配查询已不再支持，需要使用bool查询 |
Post |
{ "query":{ "terms":{ "ManagerName":["富","宇","财","富"] ,"minimum_match": 1 } } } |
|
|
query_string +-前面注意要有一个空格 |
Post |
{ "query":{ "query_string":{ "query":" +ManagerName:财富广场 -ManagerName:广场" } } } |
过滤器
|
Filter 查询 Filter查询不同时支持bool、or、and、exists、missing查询 |
Post |
http://172.16.20.49:9200/zuhe/zuheentity/_search |
{ "filter": { "bool": {"should": [{"term":{"ManagerName":"世"}} ,{"term":{"ManagerName":"界"}} ], "must_not": {"term": {"ManagerName":"水"} } } } } |
|
Query 语义查询 |
Post |
http://172.16.20.49:9200/zuhe/zuheentity/_search |
{ "query": { "bool": {"should": [{"term":{"ManagerName":"世"}} ,{"term":{"ManagerName":"界"}} ], "must_not": {"term": {"ManagerName":"水"} } } } } |
|
Filter、query联合查询 |
{ "filter": { "bool": {"should": [{"term":{"ManagerName":"世"}} ,{"term":{"ManagerName":"界"}} ], "must": {"term": {"ManagerName":"水"} } } } ,"query": { "bool": {"should": [{"term":{"ManagerName":"世"}} ,{"term":{"ManagerName":"界"}} ], "must_not": {"term": {"ManagerName":"界"} } } } } |
高级查询：
首先建立mapping关系，表示在type1对应的文档中，包含一个obj1的对象；
{
"type1" : {
"properties" : {
"obj1" : {
"type" : "nested"
}
}
}
}
嵌套查询，
{
"query":{
"nested" : {
"path" : "obj1",
"query" : {
"bool" : {
"must" : [
{
"match" : {"obj1.name" : "善亮"}
}
]
}
}
}
}
}
父查询、子查询同样，先建立mapping关系；
Put
http://172.16.20.49:9200/testindex/
“”{
"mappings": {
"grouptype": {
"properties" : {
"groupid" : {
"type" : "long"
}
}
},
"person": {
"_parent": {
"type": "grouptype"
}
}
}
}
插入元素：
http://172.16.20.49:9200/testindex/person/1?parent=1
{
"name":"zhan san",
"age":"10"
}
查询父：
http://172.16.20.49:9200/testindex/grouptype/_search
{
"query": {
"has_child": {
"type": "person",
"query": {
"match": {
"age": 10
}
}
}
}
}
https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-parent-field.html
查询子：
http://172.16.20.49:9200/testindex/person/_search
{
"query": {
"has_parent": {
"type": "grouptype",
"query": {
"match": {
"groupname": "搜索组"
}
}
}
}
}
分组统计：
{
"query": {
"filtered": {
"filter": {
"missing": {
"field": "Zhlx"
}
}
}
},
"size": ,
"aggregations": {
"tag": {
"terms": {
"field": "Permit",
"size":
}
}
}
}
post
批量插入：
{ "index": { "_index": "user","_type": "userinfo","_id": "6321113681837248" } }
{"uid":"6321113681837248","sid":"10000017","displayname":"ZYH","level":"3","introduce":"Good Luck"}
