Hi,
I’m afraid that is not possible. The phrase “BPE2B75W100/S6471” will not return that page as the result, because that page only contains a PDF viewer embed, that is not possible to fetch – that would require some very specific custom coding. When the plugin parses the contents of that page, it only sees the raw data in the database, the PDF contents are not actually there – it is rendered on the browser only.
