-Returns entries which match all provided parameters, where ``title``, ``username``, ``password``, ``url``, ``notes``, ``path``, and ``autotype_sequence`` are strings, ``string`` is a dict, ``autotype_enabled`` is a boolean, ``uuid`` is a ``uuid.UUID``.  This function has optional ``regex`` boolean and ``flags`` string arguments, which means to interpret search strings as `XSLT style`_ regular expressions with `flags`_.
