How to configure tracker3?

I am giving gnome another try. I am currently struggling with tracker3. I can not find good information in the web how to configure it and what tracker3 is actually supposed to do. Here is an example of what I mean.

tracker3 has indexed my files:

# tracker3 status                                                              
Currently indexed: 17994 files, 1380 folders
Remaining space on database partition: 52,8?GB (33,12%)
All data miners are idle, indexing complete
13 recorded failures

Somehow it does seem to track my home directory multiple times:

# tracker3 index
Path                                                                                                      Recursive                         
/home/matthias/Schreibtisch                                                                               *
/home/matthias                                                                                            *
/home/matthias/Musik                                                                                      *
/home/matthias                                                                                            *
/home/matthias/Videos                                                                                     *
/home/matthias                                                                                            -
/home/matthias                                                                                            -

It also finds files multiple times at the same location

# tracker3 search interbench-output.ods
Results:
  file:///home/matthias/interbench-output.ods
  interbench-output.ods

  file:///home/matthias/interbench-output.ods
  interbench-output.ods

For some files I can search by content and find them:

# tracker3 search "total number of events:"
Results:
  file:///home/matthias/kernel-benchmark.txt
  ?10.0020s     total number of?

But for others this does not work. I have create a file /home/matthias/Dokumente/TEST.xyz123 with content:

# cat /home/matthias/Dokumente/TEST.xyz123
es ist ein test
Aloa Hipipi

I can find the file by a partial name search:

# tracker3 search  TEST.xyz                            
Results:
  file:///home/matthias/Dokumente/TEST.xyz123
  TEST.xyz123

  file:///home/matthias/Dokumente/TEST.xyz123
  TEST.xyz123

Again it finds the file two times. Why?

But I can not search for the content of the file:

# tracker3 search "Aloa Hipipi"            
Results:

This is all totally inconsistent.

Furthermore I do not see the corresponding settings with dconf-editor.

This is what gsettings finds:

# gsettings list-recursively |grep -i tracker

ca.desrt.dconf-editor.Settings saved-view '/org/freedesktop/tracker/'

But in dconf-editor I only see a section called tracker and not Tracker3:

# dconf list /org/freedesktop/        
tracker/

I am really lost here. Any help is appreciated.

I guess I sorted this out. I had to reset everything:

  1. I used gsettings set org.freedesktop.Tracker3.Miner.Files index-recursive-directories ... to only contain my home directory
  2. I did reset the tracker3 index:
    tracker3 reset -sr and
    tracker3 reset -f [all directories that have been index so far]

This basically did the trick.

The only open question that remains is: Why cant I configure “org.freedesktop.Tracker3....” with dconf-editor?
