As a total newbie to FARR... and as one who has clearly not investigated all the remarkable features of this program...I hope my input may still be worthwhile.

I have temporarily migrated to Win from Linux where I used a similar,  and much less mature program called Synapse. It uses a third-party background daemon to index content by type (app / audio/ video / image/  document). I believe it also schedules a raw indexing of dir/file names daily, using cron and updatedb.

The hot key dialog (Ctrl-Alt) lets me 1) quickly choose the content type from a small menu bar , and  2) provides a text field to key in the file/ dir name  I'm searching for.

These days, intuitive search for video vs. audio vs. images vs. apps vs. text is becoming a natural approach.
