💡 Hint

Common Mistakes

Using match without specifying a field causes errors.

Using term or range queries when you want all documents.

The match_all query returns all documents in the index. It is the simplest search query in Elasticsearch.

Complete the code to search for documents where the field 'title' matches 'Elasticsearch'.

Elasticsearch

{
  "query": {
    "match": {
      "[1]": "Elasticsearch"
    }
  }
}

💡 Hint

Common Mistakes

Using a wrong field name like content or author.

Leaving the field name blank.

The match query searches for the given text in the specified field. Here, we want to search in the title field.

Fix the error in the query to correctly search for documents with 'status' equal to 'active'.

Elasticsearch

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

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

Aactive

B"active"

C{ "value": "active" }

D["active"]

💡 Hint

Common Mistakes

Not putting the value in quotes.

Using an array or object instead of a string.

The term query requires the value to be a string enclosed in quotes. So, "active" is correct.

4fill in blank

hard

Fill both blanks to create a range query that finds documents with 'age' greater than or equal to 30.

Elasticsearch

{
  "query": {
    "range": {
      "[1]": {
        "[2]": 30
      }
    }
  }
}

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

💡 Hint

Common Mistakes

Using gt instead of gte when equality is needed.

Using wrong field names.

The range query uses the field name and the operator. Here, age is the field and gte means 'greater than or equal to'.

5fill in blank

hard

Fill all three blanks to create a bool query that must match 'python' in 'tags' and filter documents with 'published' date after '2020-01-01'.

Elasticsearch

{
  "query": {
    "bool": {
      "must": {
        "match": {
          "[1]": "python"
        }
      },
      "filter": {
        "range": {
          "[2]": {
            "[3]": "2020-01-01"
          }
        }
      }
    }
  }
}

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

Atags

Bpublished

Cgt

Dgte

💡 Hint

Common Mistakes

Using gte instead of gt if strictly after date is needed.

Mixing up field names.

The must clause matches the term 'python' in the tags field. The filter clause uses a range query on the published field with gt (greater than) to find dates after '2020-01-01'.
