     * `search_word` as exactly `hdr.code ILIKE ... OR hdr.name ILIKE ...`, and
     * defaults to `status != 'DELETED'` when no status is sent. This is a
     * like-for-like replacement of the old WHERE clause.
     *
     * One request now instead of one subquery plus one call per hit. The old per-hit
     * call passed `hdr_guids`, which InventoryItemQueryCriteria does not define
     * (its guid filter is `guids`), so it matched nothing in particular -- another
     * reason the single query is the better shape.
