I think GNOME Activity Journal is able to track extended attributes. I couln't find anything about Tracker, so I made a file and added an attribute to test it:
$ echo "Lorem ipsum sit amet consectetur" > ./x.txt $ setfattr -n user.testing -v "this is a test" x.txt
Then run tracker-search "this is a test"
and you get 0 results. If you run tracker-control -F
, this will show you that all process are done indexing your files. Conclusion: it doesn't work on extended file attributes.
