Query the payee-seat billing-document search rows ("invoices I issued") — the V3 recreation of legacy /search/invoice-row for the member seat. Identical execution model to /search/payee-rows: every filter — equality included — runs inside the Atlas $search pipeline against the materialized row collection; this endpoint never touches the operational database. When filter[searchString][eq] is present, results are relevance-ranked (searchScore descending) with any explicit sort[field] applied as the secondary sort; when absent, default sort is dueDate descending (the legacy default). Rows include the synthetic payment records legacy callers hid from invoice lists (metadata.invoiceType = approvedInvoicesPayment) — exclude them with filter[metadata.invoiceType][ne], or select them with [eq] to list payroll aggregate documents. Account scope is enforced server-side as non-negotiable filter clauses; there is no filter[accountIds] — target a child account via X-Wingspan-Account.
