I have a collection of about 150 PDF documents hosted on a site that are all rather long, 80-500 pages each. Google indexes and searches these no problem (Google Custom Search) - they are all linked in a sitemap and in HTML pages on the site.
However, the issue is on the longer PDFs. Users are having trouble finding the relevant information because Google only returns a link to the document itself, not any reference to page number or other indication of where the term is inside of the document. And yes, of course users can use the native Acrobat search feature once they open the correct PDF, but searching twice is problematic for less savvy and impatient users.
So my question is if anyone knows of any methods to get GCS to return the page number of a PDF in search results (either via it's native output or though the API). Others have suggested simply saving each page of these documents as a separate PDF, but with over 100,000 total pages that isn't really a practical solution.
