💡 Hint

Common Mistakes

Using a string like 'doc1' instead of the numeric id '1'.

Omitting the document id.

The document id is '1', so the URL should end with /_doc/1.

💡 Hint

Common Mistakes

Using 'Elastic search' with a space breaks the match.

Using underscores or extra words changes the search meaning.

The correct search term is exactly 'Elasticsearch' to match the title field.

4fill in blank

hard

Fill both blanks to create a query that searches for 'John' in the author field and sorts results by 'publish_date' descending.

Elasticsearch

GET /books/_search
{
  "query": {
    "match": {
      "[1]": "John"
    }
  },
  "sort": [
    {"[2]": {"order": "desc"}}
  ]
}

💡 Hint

Common Mistakes

Searching in the wrong field like 'title'.

Sorting by a non-existent or incorrect field.

The query searches the 'author' field for 'John' and sorts by 'publish_date' in descending order.

5fill in blank

hard

Fill the blanks to create an aggregation that counts documents per 'genre' and filters genres with more than 5 documents.

Elasticsearch

GET /books/_search
{
  "size": 0,
  "aggs": {
    "genres_count": {
      "terms": {
        "field": "[1]",
        "min_doc_count": [2]
      }
    }
  },
  "query": {
    "match_all": {}
  }
}

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

💡 Hint

Common Mistakes

Using the wrong field like 'author' for aggregation.

Setting 'min_doc_count' too high or too low.

The aggregation counts documents by 'genre' field and filters to only include genres with at least 5 documents.
