#3 & #14 XP-Man (and #13 Roland):
Per your "conversation" on Nov. 3, 2014 on the page for "Giveaway of the Day - PDF Compressor Pro 3.0" :

...regarding the earlier GOTD offer for FileSearchy 1.3 of a few days earlier:

Did you figure out a way to contact each other? I've often wanted to be able to do that (private conversation) after reading GOTD comments, although I suppose the forums are for that purpose. I'll check the forums after submitting this -- maybe there's a FileSearchy Pro thread started you're already using!
Anyway, I too, am very interested in good file-search programs. Are you talking about something that fast-searches the CONTENTS of files (and hopefully the file/folder names as well in the same package), possibly using indexes to speed the results?
For the last couple of years I have been VERY satisfied to use Locate32 for file and folder NAMES. After proper setup of the database of drives to process (local, detachable, networked), and enabling/disabling of the extensive features, I find that it works great, very fast, thorough, low system impact and is easy to use. When I last tried for support the friendly developer responded quickly. Sad, however bug-free and well it still works, to see it is no longer being developed -- I hope he might change his mind.
(Working with computers since before the PDP and later VAX days (OK, actual punch cards -- wow, now that taught me to type carefully!), I don't need a cartoon-like "modern" interface. Filling in well-laid-out blank fields on a simple form works just fine.)
Also, for file CONTENTS I have been using dtSearch for nearly a decade; but, amazingly, it does not work for the file or folder names themselves -- duh -- at least not the edition I'm still using. For that I had scheduled the generation of a directory-dump file containing all filenames/folders for each indexed drive... or more recently simply use Locate32 since discovering it a couple of years ago!
dtSearch (.com) is a mid-priced (for many years $200 for the desktop edition), very mature commercial/industrial-strength program that is VERY powerful with many search options (expressions, binary & fuzzy searching, near-within, etc.) and features, and can index most ANY type of file most anywhere accessible on or by a network -- binaries, documents, XML, OCR, media file meta-data, e-mail PST, etc.
For as long as I have used it, it has been worth every penny for the time saved in finding stuff no matter where it lurked. My initial challenge was to rule out what it should NOT index for search!
A copy of dtSearch running on a local machine can search indexes generated remotely on other machines to reduce network traffic and speed results (pretty amazing to see in action on my own LAN on my old machines), and also includes "spider walking" the online content of websites to the page depth or other linked websites as you desire.
However, dtsearch has a fairly non-friendly "professional" mostly-text-based user interface that takes a while to explore and get used to. I've been hoping for years that someone would write a general purpose "public" GUI front-end for it (now THERE's an opportunity!) as many custom-tailored ones have been professionally written by consultants for specific industries and/or clients.
One last plug (I know, I sound like I work for them, but I don't!): Whenever I've contacted dtSearch for support (email, Yahoo! Group forums, a phone call to actual people!) they have been very responsive and friendly.
I have yet to try X1 search which, from my own "research", I understand strikes the best balance between price ($50 dollars?), features and performance among those applications in the class alongside Google Desktop Search aka GDS (no longer supported, and I found too intrusive and slowed my PC a lot), Copernic (free version obsolete, stripped down and with issues), etc.
So if you have released a similar application (or plan to), I'd be happy to know about it -- Thanks!
