Async search for expensive queries in Elasticsearch - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to start an async search request.

Elasticsearch

POST /[1]
{
  "query": {
    "match_all": {}
  }
}

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

💡 Hint

Common Mistakes

Using /start which is not a valid endpoint.

Using /query which is incorrect.

The endpoint /_async_search starts an async search request.

2fill in blank

medium

Complete the code to retrieve the async search result by ID.

Elasticsearch

GET /_async_search/[1]

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

Asearch_id

Bstatus

Cyour_async_search_id

Dresult

Attempts:

3 left

💡 Hint

Common Mistakes

Using generic words like 'result' or 'status' instead of the actual ID.

Trying to get results without specifying the ID.

You must replace {{BLANK_1}} with the actual async search ID returned when starting the search.

3fill in blank

hard

Fix the error in the async search request to set the wait_for_completion_timeout to 1 second.

Elasticsearch

POST /_async_search?[1]=1s
{
  "query": {
    "match_all": {}
  }
}

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

Await_timeout

Bwait_for_completion_timeout

Ctimeout

Dcompletion_timeout

Attempts:

3 left

💡 Hint

Common Mistakes

Using shortened or incorrect parameter names like 'timeout' or 'wait_timeout'.

Misspelling the parameter name.

The correct parameter to set the wait time for async search completion is wait_for_completion_timeout.

4fill in blank

hard

Fill both blanks to create an async search request that keeps the search alive for 5 minutes and returns partial results.

Elasticsearch

POST /_async_search?[1]=5m&[2]=0s
{
  "query": {
    "match": {
      "message": "error"
    }
  }
}

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

Akeep_alive

Bwait_for_completion_timeout

Cbatched_reduce_size

Dkeep_on_partial

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing keep_alive with wait_for_completion_timeout.

Using parameters that do not exist like keep_on_partial.

keep_alive=5m sets how long the async search is kept alive. wait_for_completion_timeout=0s returns partial results immediately.

5fill in blank

hard

Fill in the blank to create a request that cancels an async search by its ID.

Elasticsearch

DELETE /_async_search/[1]

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

Ayour_async_search_id

Bid

Ccancel

Dsearch_id

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'cancel' as the ID in the path.

Adding unnecessary query parameters like ?id=...

The endpoint is DELETE /_async_search/<your_async_search_id> to cancel an async search.
