1fill in blank

easy

Complete the code to create a basic bool query with a must clause.

Elasticsearch

{
  "query": {
    "bool": {
      "must": [
        { "match": { "title": "[1]" } }
      ]
    }

💡 Hint

Common Mistakes

Using a word not related to the field.

Confusing must with should.

The must clause requires the title field to match the word "Elasticsearch".

2fill in blank

medium

Complete the code to add a filter clause that matches documents with status 'active'.

Elasticsearch

{
  "query": {
    "bool": {
      "filter": [
        { "term": { "status": "[1]" } }
      ]
    }
  }
}

💡 Hint

Common Mistakes

Using a status that does not exist in the data.

Confusing term with match.

The filter clause filters documents where the status field exactly matches "active".

hard

Fix the error in the bool query by completing the missing clause to exclude documents with tag 'deprecated'.

Elasticsearch

{
  "query": {
    "bool": {
      "must": [
        { "match": { "content": "search" } }
      ],
      "[1]": [
        { "term": { "tag": "deprecated" } }
      ]
    }
  }
}

💡 Hint

Common Mistakes

Using filter instead of must_not to exclude documents.

Adding the clause under should which changes scoring.

The must_not clause excludes documents matching the condition, here those tagged as "deprecated".

4fill in blank

hard

Fill both blanks to create a bool query that must match 'python' in title and should match 'tutorial' in tags.

Elasticsearch

{
  "query": {
    "bool": {
      "[1]": [
        { "match": { "title": "python" } }
      ],
      "[2]": [
        { "match": { "tags": "tutorial" } }
      ]
    }
  }
}

💡 Hint

Common Mistakes

Swapping must and should clauses.

Using filter instead of should for optional matches.

The must clause requires matching 'python' in the title, and the should clause boosts documents matching 'tutorial' in tags.

5fill in blank

hard

Fill all three blanks to create a bool query that must match 'data' in content, filters for status 'published', and excludes tag 'draft'.

Elasticsearch

{
  "query": {
    "bool": {
      "[1]": [
        { "match": { "content": "data" } }
      ],
      "[2]": [
        { "term": { "status": "published" } }
      ],
      "[3]": [
        { "term": { "tag": "draft" } }
      ]
    }
  }
}

💡 Hint

Common Mistakes

Mixing up filter and must_not clauses.

Using should instead of filter for filtering.

The must clause requires matching 'data' in content, filter restricts to status 'published', and must_not excludes documents tagged 'draft'.
