Index operation of elasticsearch

1. Create an index (test_index)

curl -XPUT "http://192.168.99.1:9200/test_index"

 2. Create an index and specify the number of shards and replicas

curl -XPUT "http://192.168.99.1:9200/test_index" -d'
{
  "settings": {
    "number_of_shards": 2,
    "number_of_replicas": 1
  }
}'

 3. Create an index (test_index), create a type (product), and specify the mapping data

curl -XPUT "http://192.168.99.1:9200/test_index" -d'
{
  "mappings": {
    "product" : {
      "properties": {
        "id" : {
          "type": "text",
          "index": "not_analyzed"
        },
        "userName" : {
          "type": "text",
          "index": "analyzed"
        }
      }
    }
  }
}'

 4. The value of the field in the mapping of the existing type cannot be modified, but it can be added

curl -XPOST "http://192.168.99.1:9200/test_index/_mapping/product" -d'
{
      "properties": {
        "price" : {
          "type": "long"
        }
      }
}'

 5. Add a new type to the existing index

curl -XPOST "http://192.168.99.1:9200/test_index/_mapping/add_new_type" -d'
{
  "properties": {
    "field01" : {
      "type": "text"
    }
  }
}'

 6. Close the index

curl -XPOST "http://192.168.99.1:9200/test_index/_close"

 7. Open the index

curl -XPOST "http://192.168.99.1:9200/test_index/_open"

 8. Get the information under the index

curl -XGET "http://192.168.99.1:9200/test_index"

 9. View index statistics

curl -XGET "http://192.168.99.1:9200/test_index/_stats"

 10. Get the mappings of the index

curl -XGET "http://192.168.99.1:9200/test_index/_mappings"

 11. Delete the index

curl -XDELETE "http://192.168.99.1:9200/test_index"

 12. Cancel the automatic index creation of es and modify the configuration file of es

action.auto_create_index: false

13. Create aliases for indexes (_alias is used for a single operation, while _aliases is used for multiple operations, maintaining atomicity)

     method one:

    
     Method two:

curl -XPUT "http://192.168.99.1:9200/test_index/_alias/alias_new_index"

 14. Modify the index alias ( delete first and then add )

curl -XPOST "http://192.168.99.1:9200/_aliases" -d'
{
  "actions": [
    {
      "remove": {
        "index": "test_index","alias": "alias_index"
      }
    },
    {
      "add": {
        "index": "test_index","alias": "alias_new_index"
      }
    }
  ]
}'

 15. Delete index aliases

    method one:

curl -XPOST "http://192.168.99.1:9200/_aliases" -d'
{
  "actions": [
    {
      "remove": {
        "index": "test_index","alias": "alias_new_index"
      }
    }
  ]
}'

    Method 2: (delete the alias that the index starts with test and the alias is alias_new_index)

curl -XDELETE "http://192.168.99.1:9200/test*/_aliases/alias_new_index"

 16. Query all aliases under the test_index index

curl -XGET "http://192.168.99.1:9200/test_index/_alias/*"

 17. The query alias alias_new_index is associated with those indexes

curl -XGET "http://192.168.99.1:9200/_alias/alias_new_index"
