💡 Hint

Common Mistakes

Using endpoint names like 'search' or 'query' instead of the index name.

Omitting the index name before '/_bulk'.

The bulk API requires the target index name in the URL path. Here, my_index is the correct index name placeholder.

Using numeric ID without quotes causing errors.

Common Mistakes

Using single quotes instead of double quotes.

Leaving string values unquoted.

4fill in blank

hard

Fill both blanks to set the bulk request header and body for indexing two documents.

Elasticsearch

{"index": {"_index": [1]
{"field": "value1"}
{"index": {"_index": [2]
{"field": "value2"}

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

A"my_index"

B"other_index"

C"myIndex"

D"index"

💡 Hint

Common Mistakes

Using invalid index names or missing quotes.

Using camelCase index names which are not standard.

Each bulk action must specify the target index. Here, the first document goes to "my_index" and the second to "other_index".

5fill in blank

hard

Fill all three blanks to create a bulk request that indexes documents with IDs and fields correctly.

Elasticsearch

{"index": {"_index": [1], "_id": [2]
{"name": [3]

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

A"users"

B"42"

C"Alice"

D"products"

Attempts:

💡 Hint

Common Mistakes

Using unquoted strings for IDs or field values.

Mixing index names or using invalid names.

The bulk request header specifies the index "users" and document ID "42". The document source includes the field "name" with value "Alice".
