Initialise an instance.

:param locators: The list of locators to search.
:param kwargs: Passed to the superclass constructor,
               except for:
               * merge - if False (the default), the first successful
                 search from any of the locators is returned. If True,
                 the results from all locators are merged (this can be
                 slow).
