Remember that I don't want to use full-text search across sessions/restarts
Since 3.26 or so, Nautilus does a "full text" search instead of filename search when I start typing within a folder. Thankfully it lets me go into the search's dropdown menu to switch it to filename search only... but it doesn't remember that choice across sessions. Once you quit Nautilus (or logout, reboot, etc.) and the process ends, the next time you run a search it will be back to doing a "full text search".
