re-index a number records specified by the given ids. Use for large
 indexing jobs i.e. after modifying a lot of records with Ferret disabled.
 Please note that the state of Ferret (enabled or disabled at class or
 record level) is not checked by this method, so if you need to do so
 (e.g. because of a custom ferret_enabled? implementation), you have to do
 so yourself.
