Lightroom :: Finding Filenames Or Folders In Libraries Over Volumes?

for rendering purposes (we work on stop-motion-stop films) in our company's processing workflow, I export many different image sequences with 1000 or more JPG images from many different RAW NEF folders. All these folders with 1000s of RAW NEF files get developed and then exported as JPGs
 
- into folders on various volumes on servers. so other people then further render from these folders in AE or other hosts.
 
sometimes however, after a week or month, for whatever reason we need to re-develop original RAW NEFs of a folder of a specific set in it's original lightroom folder (from where those JPGs had been exported from).
 
By knowing a filename like for example _DSC7561.jpg out of a JPG export folder I then would like to quickly find and locate the original folder within the LR4 library, containing e.g. the file _DSC7561.nef from where that JPG was exported from (for specific reasons I can not change all those export JPG folders are on different volumes than the original folders with RAW file sequences).
 
So, when I sit in front of LR4 on the RAW development stations is there a way to find
 
- folders in the lightroom catalogue in volumes or over volumes (by their known folder name or part of their foldername)?
 
- filenames or part of filenames in folders over volumes, or within a volume?
 
it is so time consuming to scroll all folders to find an original folder with RAWfiles from where we developed and exported JPGs. we keep those RAW folders not only for the original RAW files of course, but also because of the XMP sidecar files with all the development changes. sometimes we even store snapshots or several stages of XMP processing to them. 
 
Of course LR4 offers search for a filename within a folder via CMD+F, but we don't need that actually.
 
we need CMD+F for the library search for foldernames or folders over a volume at least, but better would be various volumes.
 
are there any LR4 plugins or tools that solve this? Or did I oversee something?
 
I can of course search for any folder containing a file _DSC7561.nef outside of LR4 in finder with tools like "Tembo" or "Find any File" easily, but that don't jumps me to the folder in the LR4 library, with all my developement changes.
 
PS: we don't use keywords, it is not possible with TB of images each week but we use specific sequencing names for image file sequences and structured folders of course.
