💡 Hint

Common Mistakes

Using a different name than the intended search term.

Leaving the value empty or misspelled.

The fuzzy query requires the exact value to search fuzzily. Here, "Jon" is the intended search term.

medium

Complete the code to set the fuzziness level to 2 in the fuzzy query.

Elasticsearch

{
  "query": {
    "fuzzy": {
      "name": {
        "value": "Jon",
        "fuzziness": [1]
      }

💡 Hint

Common Mistakes

Using quotes around numbers which makes them strings.

Using an unsupported fuzziness value.

The fuzziness level controls how many edits are allowed. Setting it to 2 means up to two edits are accepted.

3fill in blank

hard

Fix the error in the fuzzy query by completing the missing key for the search term.

Elasticsearch

{
  "query": {
    "fuzzy": {
      "name": {
        [1]: "Jon",
        "fuzziness": 1
      }
    }
  }
}

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

C"query"

D"match"

💡 Hint

Common Mistakes

Using incorrect keys like "term" or "match" inside the fuzzy query.

Omitting the key and only providing the value.

The fuzzy query requires the key "value" to specify the search term.

4fill in blank

hard

Fill both blanks to create a fuzzy query that searches the "title" field for "elastic" with fuzziness 1.

Elasticsearch

{
  "query": {
    "fuzzy": {
      [1]: {
        "value": [2],
        "fuzziness": 1
      }
    }
  }
}

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

A"title"

B"elastic"

C"name"

D"elasticsearch"

💡 Hint

Common Mistakes

Mixing up field names and values.

Not quoting the strings properly.

The field to search is "title" and the fuzzy value is "elastic".

5fill in blank

hard

Fill all three blanks to create a fuzzy query on the "description" field with value "search", fuzziness "AUTO", and prefix length 2.

Elasticsearch

{
  "query": {
    "fuzzy": {
      [1]: {
        "value": [2],
        "fuzziness": [3],
        "prefix_length": 2
      }
    }
  }
}

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

A"description"

B"search"

C"AUTO"

D"searching"

Attempts:

💡 Hint

Common Mistakes

Using numeric fuzziness instead of "AUTO" when asked.

Forgetting to quote string values.

Confusing prefix_length with fuzziness.

The field is "description", the value is "search", and fuzziness is set to "AUTO" for automatic adjustment.
