> So the question is: how do you know, whether /some/random/file has been modified while your daemon or application wasn't running or the filesystem wasn't mounted on your system, without performing a stat call on it? If you don't have an answer to that, which also needs to be orders of magnitudes faster, then you'll never match the performance of Everything.
Well, my intention is to match the feature list of Everything, but on Linux, and as far as I knew, Everything did not have full support for external drives - you'd have to convert them to NTFS, or add them to be indexed manually.
The use-case I've seen for Everything has always been for a local user searching their local PC; I wasn't even sure until now that Everything can sometimes search transient filesystems because know one I ever saw using it used it for files on a transient filesystem.
You're correct; what I cannot do is monitor transient filesystems; but doing permanent filesystems at a speed better than or equal to Everything is still better than anything I've used on Linux, many of which don't even search system files, nevermind transient filesystems. And they all use the locate db which is always a day or so out of date.
And yes, it can be done purely by monitoring filesystem changes. Sure, a full index needs to be built the first time, but that's a one-off cost - index updates after that should be fast enough to do for each write/remove/move operation that you can update the index dozens of times per second.
For non-transient filesystems, performance should be the same as, or better than, Everything.
