💡 Hint

Common Mistakes

Not using quotes around the field name.

Using single quotes instead of double quotes.

The field name must be a string in quotes. Without quotes, it causes a syntax error.

💡 Hint

Common Mistakes

Using "city" instead of "address.city".

Using incorrect key names like "value".

The key must be "field" and the value the full field name "address.city" to check nested fields.

          "exists": {

💡 Hint

Common Mistakes

Using "age" instead of "profile.age".

Using wrong keys like "value" or missing the bool must clause.

The exists query uses the key "field" with value "profile.age". The bool query uses "must" to require this condition.
