I'm very interested in this discussion.
Desktop or NAS/Network, index/search seems to be a perennial problem.
I too was desolé when Google Desktop Search (GDS) was killed off by Google.
I have found nothing to replace it. It's departure has left a vacuum.
At one time GDS could find pretty much everything,
. including inside archived files, Gmail, Outlook, and your other PCs.
Mind-blowingly powerful search of the virtual unified desktop - cloud and client-based. But then, because cosporate users raised objections, Google started to lop off its limbs.
It was always in ß, sometimes locked up the CPU or needed to have its indexing restarted from scratch to work around some internal bug.
But nothing else quite like it.
On the other hand, where search should arguably been one of its strongest features, Microsoft Windows indexing/search was a singular weakness. Whether it even did what it was designed to do was not the issue - it never
worked effectively/efficiently in XP - it was simply infeasible. It was such a resource hog that it was the first thing you had to turn off to restore your computer's performance potential.
Then, in Win7 it began to look as though Microsoft Windows indexing/search had finally been rebuilt using modern technology. Oops, wrong. It starts off really well, but then, after a while, you can't find those files that you know
you have and which were originally showing up in searches. What gives?
Microsoft seems to be silent other than offering the useless suggestion that you reset your settings or rebuild the probably corrupted index. The thing is, it shouldn't be failing so easily in the first place. Not fit for purpose.
What are/were the options for search?
Just to kick things off, I put up this list here at EditPad
: Summary of Search Tools
It's open to public use (read/write access).
Might this be of use as a running tally of what we know about the various search software for this discussion? Update it as you see fit.
I am also looking elsewhere (e.g., incl. Wikipedia) for a summary of search tools that we might be able to add to the discussion.
