    search: remove redundant check
    
    We check for (metasNeeded.length == 0) at the beginning of the function,
    which is only ever called when when a non-zero number of results is
    received back from the provider. Effectively, this means that
    (metas.length != metasNeeded.length) will also catch (metas.length == 0)
    and print a nicer message to the log.
