Only make searchable a specific subset of fields

🔗 Playground link: a dynamic string field is automatically searchable

Make it so only fields under the metadata structure are indexed (and thus this query would then fail to find any matching documents). This is an exercise where no matching documents (an empty array []) is the goal, rather than matching on a field that should not be indexed.

Solution

Turn off top-level dynamic mapping, and only index the metadata sub-structure.

{
  "mappings": {
    "dynamic": false,
    "fields": {
      "metadata": [
        {
          "type": "document",
          "dynamic": true
        }
      ]
    }
  }
}
