💡 Hint

Common Mistakes

Putting the number in quotes making it a string

Using the word "three" instead of the number

Using an unrelated string like "shards"

The number of shards must be a number, so 3 without quotes is correct.

    "properties": {
      "title": {
        "type": "[1]"
      }
    }

💡 Hint

Common Mistakes

Using "string" which is not a valid type in recent Elasticsearch versions

Using "keyword" which is for exact matches, not full text

Using "field" which is invalid

"text" is the correct type for full-text searchable fields in Elasticsearch.

💡 Hint

Common Mistakes

Putting refresh interval as a number without quotes

Using wrong numbers for replicas

Using invalid time units

Number of replicas is a number (2), and refresh interval is a string with time unit ("1s").

Fill all three blanks to create a mapping for a "date" field named "publish_date" with format "yyyy-MM-dd".

        "type": "[2]",

💡 Hint

Common Mistakes

Using "text" as type instead of "date"

Using wrong format strings

Mixing field name and type

The field name is "publish_date", type is "date", and the format is "yyyy-MM-dd" for year-month-day.
