Ash extension that mirrors a resource into a SearchAsh.GlobalIndex so it shows up in the unified global search.

defmodule MyApp.Sales.BonDeCommande do
  use Ash.Resource,
    domain: MyApp.Sales,
    data_layer: AshPostgres.DataLayer,
    extensions: [SearchAsh.Source]

  searchable do
    index MyApp.Search.Document
    source_type :bon_de_commande
    fields [:numero, :client_nom, :description]
    language_attribute :language
    label_field :numero
    archived :deleted_at         # optional — truthy value marks the row archived
  end

  # ... attributes + create/update/destroy actions ...
end

The extension sets require_atomic? false on the update/destroy actions it augments (the sync stems through a NIF and can't run in an atomic SQL statement), so you don't set it yourself. Because the sync writes only to the separate index table (never to a source attribute), it is atomic-compatible: Ash.bulk_create/bulk_update/bulk_destroy keep the index in sync with no strategy: option required.

On create/update it upserts a stemmed document into the index (tenant-aware). archived derives the index flag from a source attribute's truthiness (a boolean, or a deleted_at timestamp) or a record -> boolean function; :global_search hides archived rows by default. On destroy, on_destroy either removes the row (:remove, default) or keeps it archived (:archive, for AshArchival-style soft deletes).

Backfill existing rows with SearchAsh.reindex(MyApp.Sales.BonDeCommande).
