Not bad! I haven't thought of it!
I immediately typed Wamp and got:
Web Photo Album, Where are my Autocad template files, WAMP (Apache), i-Sound WMA MP3 Recorder and finally Winamp plus another 20 various links!
Typing Tbird I got:
TV recorder GBPVR documentation Wiki, Extreme Thumbnail Generator, Realtek Gigabit and Fast NIC Driver, Video editor Virtual Dub and finally Thunderbird and another 20 additional unrelated links!
May be I would save 1 second typing the (nearly) full name but then I loose several second searching for the correct answer!
 :D
May be it would give better results by giving a higher score to the "closiness" and the "sequentiality" of the letters. i.e. Thundirbird should have a higher ranking than TV recorder GBPVR documentation Wiki or even Bird watching

I tested your FARR but got very strange results.
For instance when I type "Ransack" I get 3 results clearly related to the search item.
But the 4th result is "Ruler with angles, color capture pickpick_inst.exe" !
The 5th result is OK but the 6th is "I:\_Download\Image Stacker (enhance dark images) SW  (ROTTO) imgstack.zip"
7th to 11th are OK again and the I get a whole bunch of results with absolutely no "Ransack" in the file name.
Can somebody tell me what I am doing wrong?
