Title: Use nonconflicting param name for search filtering

`:domain` is a reserved term for rails `url_for` helper and isn't possible to bypass.

Rename the query string parameter to `datahub` which has mostly the same connotation apart from implying that it will be an exact match to the whole domain which is probably better and means the search filter could be indexed and optimised.
