Google: how to index documents linked to from a page, but not the page itself?
===

I have a web page on a new website which lists a load of PDF documents transferred from an old site, the idea being that I can point Google to this page via on demand indexing for Site Search and have all the PDFs indexed for the new site. Trouble is I've noticed the URL for the page itself occasionally appearing in the search results, which I don't want (it has no styling -- it's just an HTML list).

I'm wondering if it's possible to prevent Google's index from including the page itself, but keep it happily indexing the files it links to.

I've tried 

    header('X-Robots-Tag: noindex');

on the page but I'm not yet sure if that has worked. Assuming it does for the page itself, is it safe to assume that the documents the page links to won't 'inherit' the instruction not to index?
