- 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
