Search the cited limits, species registers and permits by free text

A query is read by exact matches against what is held: an NPDES permit number, a CAS number, a place's ISO code or name, a parameter name as a regulation prints it, a scientific name or a common name a species register prints, words of an instrument's title. Each result is an id for /fetch, a title saying what it holds, and the url of the page with the same rows. searched says how the query was read and names what was read but is not held. Nothing found is a refused block (search.none_held) saying what was searched.
