SearchResponse

Response shape of the Typesense-backed /search endpoints (clients, invoices, payments,
receipts). Distinct from ListResponse: it reports found (total matches) rather than
has_more/total_results, and it has no cursor. It is also not the standardized
envelope — data is top-level.

These endpoints require both a q (or query) parameter and a Typesense key configured
on the team; either missing yields 400 with missing_query / missing_typesense_key.
