you know you just gave me a really really good idea too.
i've been wanting to add a simple non-contiguous letter search mode, which would let you type something like:
to find: "Microsoft Office"
right now, farr supports non-contiguous words, but because there are SOOOO many possible ways to match files after you type just 2 or 3 letters, i've avoided it.
what we could do is support such a search within the history without sacrificing any real speed.
