I want this for only one specific removable volume: automatically add its files to the database when that volume is connected and clear the files from the database when the volume is unconnected. But I don't want any other removable volumes to be included in this way. So the options
"automatically include new..." and "automatically remove ..." in Options > Indexes > NTFS is not a solution.
What I instead want is a version of the "Monitor changes" option for that volume that reacts to volume unconnect by clearing all files on that volume from the database.
Is there some other way to achieve that in Everything?
