USE THIS TOOL WHEN searching UK Acts and Statutory Instruments by title, phrase, or full-text.
Returns ranked results: title, type, year, number, legislation.gov.uk URL,
and next_steps hints (toc URI, section template). AFTER calling, chain
to legislation_get_toc then legislation_get_section for structural drill-in.
Filter discipline: `type` and `year` are exact-match. Use only when you
already know the value. For currency-driven searches ("the recent
Renters' Rights Act"), query by phrase alone and read the year from the
results — guessing a year and filtering by it zeroes results when wrong.
For broader concept queries across content, set `fulltext=True`.
