I've managed to get into the searching system such that my content is now being indexed/searched successfully, likewise I managed to setup a new indexset which searches the PDF's that are loaded. All using fuzzy searching on multiple words so am making good progress.

Challenge is that I only want to have those PDFs appearing in the search results that are referenced by the content. Basically, because PDF's dont have the ability to be unpublished then we have to rely on the content publish methods for docs that can be included in the search results - and it only really makes sense to display those PDFs within the context of there they are found - i.e. the content.

Any thoughts on how to resolve this?
