Common Mistakes

Using 'get' instead of 'index' causes errors because 'get' is for retrieving documents.

Using 'search' is invalid in bulk operations.

💡 Hint

Using '_search' endpoint instead of '_bulk' will not perform batch operations.

Using '_update' or '_delete' endpoints individually instead of bulk.

The bulk API endpoint is /_bulk which allows batch operations.

💡 Hint

Common Mistakes

Using 'index' overwrites documents instead of creating new ones.

Using 'delete' or 'update' is incorrect for adding new documents.

The create action adds a new document only if it does not exist, which is required here.

Fill both blanks to create a bulk request that updates a document and deletes another.

Elasticsearch

{ "[1]": { "_index": "products", "_id": "4" } }
{ "doc": { "price": 950 } }
{ "[2]": { "_index": "products", "_id": "5" } }

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'index' instead of 'update' will overwrite the whole document.

Using 'create' instead of 'delete' will cause errors.

The first action is update to change the price, and the second is delete to remove a document.

5fill in blank

hard

Fill all three blanks to build a bulk request that indexes a new document, updates another, and deletes a third.

Elasticsearch

{ "[1]": { "_index": "products", "_id": "6" } }
{ "name": "Monitor", "price": 300 }
{ "[2]": { "_index": "products", "_id": "7" } }
{ "doc": { "price": 280 } }
{ "[3]": { "_index": "products", "_id": "8" } }

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'index' instead of 'create' may overwrite documents.

Mixing up 'update' and 'delete' actions causes errors.

The first action is create to add a new document only if it doesn't exist, the second is update to modify an existing document, and the third is delete to remove a document.
