Lucene sort type (Alphabetical or Numeric sorting)

[Skrypt]

Lucene sort types are defined here in this documentation :

https://lucenenetdocs.azurewebsites.net/api/Lucene.Net/Lucene.Net.Search.SortFieldType.html

By default Lucene use alphabetical ordering.
Here is an example to achieve a numeric sort on a numeric field :

{
  "query": {
    "match_all": { }
  },
  "sort": [
    { "MyContenType.Amount": { "order": "asc", "type": "int32" } }
  ]
}
