🎯 Goal: Learn how to delete and close Elasticsearch indexes using simple commands.

📋 What You'll Learn

Create an index named store-products.

Create a variable index_name with the value store-products.

Write a command to close the index using index_name.

Write a command to delete the index using index_name.

Print the responses from closing and deleting the index.

💡 Why This Matters

🌍 Real World

Managing Elasticsearch indexes is important for saving resources and cleaning up old data in real applications like online stores or logging systems.

💼 Career

Knowing how to delete and close indexes is a key skill for Elasticsearch administrators and backend developers working with search and analytics.

1

Create an index named store-products

Write a command to create an Elasticsearch index called store-products.

Elasticsearch

# Your code here to create the index 'store-products'

Need a hint?

Use the PUT method with the index name store-products to create the index.

2

Create a variable index_name with value store-products

Create a variable called index_name and set it to the string 'store-products'.

Elasticsearch

PUT /store-products
{
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 0
  }
}

# Your code here to create variable index_name

Need a hint?

Use index_name = 'store-products' to create the variable.

3

Close the index using index_name

Write a command to close the Elasticsearch index using the variable index_name. Use the POST method and the _close endpoint.

Elasticsearch

PUT /store-products
{
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 0
  }
}

index_name = 'store-products'

# Your code here to close the index using index_name

Need a hint?

Use POST /store-products/_close to close the index.

4

Delete the index using index_name and print responses

Write a command to delete the Elasticsearch index using the variable index_name. Use the DELETE method. Then print the responses from closing and deleting the index.

Elasticsearch

PUT /store-products
{
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 0
  }
}

index_name = 'store-products'

POST /store-products/_close

# Your code here to delete the index and print responses

Need a hint?

Use DELETE /store-products to delete the index. Then use print() to show a success message.
