1fill in blank

easy

Complete the code to search multiple fields using a multi-match query.

{
  "query": {
    "multi_match": {
      "query": "Elasticsearch",
      "fields": [1]

💡 Hint

Common Mistakes

Using a single string instead of a list for multiple fields.

Forgetting to use quotes around field names.

The fields parameter expects a list of fields to search. Using ["title", "content"] searches both fields.

medium

Complete the code to set the multi-match query type to 'phrase'.

Elasticsearch

{
  "query": {
    "multi_match": {
      "query": "quick brown fox",
      "fields": ["title", "content"],
      "type": [1]
    }
  }
}

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

A"phrase"

B"most_fields"

C"best_fields"

D"cross_fields"

💡 Hint

Common Mistakes

Using the default type and expecting phrase matching.

Using an invalid type string.

Setting type to "phrase" makes the query look for exact phrase matches across the fields.

3fill in blank

hard

Fix the error in the multi-match query by completing the missing parameter to boost the 'title' field.

Elasticsearch

{
  "query": {
    "multi_match": {
      "query": "Elasticsearch tutorial",
      "fields": ["title[1]", "content"]
    }
  }
}

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

B*2

C:2

D^2

💡 Hint

Common Mistakes

Using incorrect symbols like * or : for boosting.

Not adding any boost and expecting higher relevance.

Adding ^2 after a field name boosts its importance by 2 in the search results.

4fill in blank

hard

Fill both blanks to create a multi-match query that searches 'title' and 'summary' fields and uses the 'cross_fields' type.

Elasticsearch

{
  "query": {
    "multi_match": {
      "query": "open source",
      "fields": [[1], [2]],
      "type": "cross_fields"
    }
  }
}

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

A"title"

B"content"

C"summary"

D"author"

Attempts:

3 left

💡 Hint

Common Mistakes

Including wrong field names like 'content' or 'author'.

Not matching the fields to the query intent.

The fields list should include "title" and "summary" to search both fields with the cross_fields type.

5fill in blank

hard

Fill all three blanks to build a multi-match query that searches 'title' boosted by 3, 'description', and 'tags' fields, using the 'most_fields' type.

Elasticsearch

{
  "query": {
    "multi_match": {
      "query": "machine learning",
      "fields": [[1], [2], [3]],
      "type": "most_fields"
    }
  }
}

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

A"title^3"

B"description"

C"tags"

D"content"

Attempts:

3 left

💡 Hint

Common Mistakes

Forgetting to boost the 'title' field.

Including unrelated fields like 'content'.

The fields list includes "title^3" to boost the title field by 3, plus "description" and "tags". The most_fields type searches all fields and combines scores.
