Search the FRED catalog - by text, by series ID, by release, or list a release's series

Discovery primitive over the full FRED catalog (~800k series). Full-text search (search_type=full_text, default), series-ID search (search_type=series_id), the list of all FRED releases (search_type=release, no release_id), or every series in one release (release_id=<id>). Returns lightweight series/release metadata - the starting point for the release-table and curve endpoints.

Attribute to order results by. Left unset, a search orders by search_rank (relevance, and FRED's own default for search) and a release listing orders by observation_end, unchanged. Ordering a broad match set by a data attribute makes FRED sort the entire set: measured on 'unemployment rate', order_by=observation_end took 63s and failed, while search_rank returned in 2.2s for the same query and limit.
