Actually it's not quite true that I haven't thought
about Glimpse in a while; I use glimpse almost every
day in my various development environments where
I have an old version (4.1 circa 1997) deployed as
part of my code analysis toolset.  Glimpse basically
pre-greps a specified collection of files, which
makes subsequent searches quite fast.  For example,
I routinely search entire kernel source trees in one
or two seconds.  Glimpse also allows searches with
configurable amounts of error-tolerance, or "fuzz" .
