- use Ferret::Index::Index instance for searching as well, as the check for   external index changes (that was the reason for the complex searcher   initialization and closing code) is implemented there, too. - search and index all attributes when no :fields option is given - add :handle_parse_errors=true default option for ferret,    so find_by_contents behaves well on invalid query strings - wildcard query-test
