Elasticsearch the index template

solved problem

　　When the index type and configuration information are the same, you can use the index template to handle, otherwise we will manually create the index.

Creating Index Template

PUT _template/2019
{
  "index_patterns": ["20*", "product1*"],   
  "settings":{   
    "number_of_shards": 2,
    "number_of_replicas": 1
  },
  "mappings":{  
    "doc":{
      "properties":{
        "ip":{
          "type":"keyword " 
        }, 
        " Method, " : {
           " of the type " : " keyword " 
        } 
      } 
    } 
  } 
} 

# index_patterns is indexed mode, refer to when creating order when the index 20 and the beginning of the product1, using the index template 
# in settings setting, we custom index assignment for the three main fragments. copied unchanged slice 
# mappings specified mapping relationship

    "aliases" : { },
    "mappings" : {
      "doc" : {
        "properties" : {
