Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a completion suggester in the search query.

Elasticsearch

{
  "suggest": {
    "song-suggest": {
      "prefix": "nirv",
      "completion": {
        "field": "[1]"
      }
    }
  }
}

💡 Hint

Common Mistakes

Using the suggester name instead of the field name.

Using a field that is not mapped as a completion field.

The completion suggester requires the name of the field that holds the completion data. Here, title is the correct field name.

2fill in blank

medium

Complete the code to add a size limit to the number of suggestions returned.

Elasticsearch

{
  "suggest": {
    "song-suggest": {
      "prefix": "nirv",
      "completion": {
        "field": "title",
        "[1]": 5
      }
    }
  }
}

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

💡 Hint

Common Mistakes

Using limit or max_results which are not valid parameters here.

Using max_suggestions which does not exist.

The size parameter controls how many suggestions are returned by the completion suggester.

3fill in blank

hard

Fix the error in the completion suggester query by completing the missing parameter.

Elasticsearch

{
  "suggest": {
    "song-suggest": {
      "prefix": "nirv",
      "completion": {
        "field": "title",
        "skip_duplicates": [1]
      }
    }
  }
}

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

A"true"

B"false"

Ctrue

DTrue

💡 Hint

Common Mistakes

Putting boolean values in quotes, making them strings.

Using capitalized True which is Python style, not JSON.

The skip_duplicates parameter expects a boolean value without quotes. So true is correct.

4fill in blank

hard

Fill both blanks to create a completion suggester with fuzzy matching enabled and a fuzziness level of 2.

Elasticsearch

{
  "suggest": {
    "song-suggest": {
      "prefix": "nirv",
      "completion": {
        "field": "title",
        "[1]": {
          "fuzziness": [2]
        }
      }
    }
  }
}

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

D"2"

Attempts:

💡 Hint

Common Mistakes

Using fuzziness as the first blank instead of fuzzy.

Putting fuzziness level in quotes.

To enable fuzzy matching, set the fuzzy parameter to an object containing fuzziness set to the integer 2.

5fill in blank

hard

Fill all three blanks to create a completion suggester that uses the prefix "nirv", returns 3 suggestions, and skips duplicates.

Elasticsearch

{
  "suggest": {
    "song-suggest": {
      "prefix": "[1]",
      "completion": {
        "field": "title",
        "size": [2],
        "skip_duplicates": [3]
      }
    }
  }
}

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

Ctrue

Dfalse

Attempts:

💡 Hint

Common Mistakes

Using skip_duplicates as a string instead of boolean.

Setting size to a string instead of a number.

The prefix is "nirv", size is 3 to limit suggestions, and skip_duplicates is true to avoid repeated suggestions.
