- the materials admin syncs after create and update and removes after delete, once the save transaction commits (UseMaterialIndex, set at Boot) - POST and PUT /api/v1/bm/materials sync after the transaction, DELETE removes the document (its statement has no primary key, so no callback) - bm:materials-reindex [--fresh] [--if-configured] ensures the index and syncs every material; it refuses without an engine and runs nightly at 04:15 with --if-configured - TestMaterialSearchAgainstDatabase (Postgres) is written for the final verification phase
