baloo indexes content even with 'only basic indexing' set to true

[chimak111]

My specs are in the sig below. System full updated.

Here's my ~/.config/baloofilerc:

[Basic Settings]
Indexing-Enabled=true

[General]
dbVersion=2
exclude filters=qrc_*.cpp,libtool,*.rej,.svn,litmain.sh,_darcs,*.la,po,__pycache__,CMakeFiles,.moc,*.o,*.gmo,.git,CMakeTmp,config.status,*.orig,*.pyc,moc_*.cpp,*.nvram,*.tmp,confstat,*.rcore,*~,confdefs.h,*.lo,.xsession-errors*,autom4te,*.csproj,core-dumps,*.elc,*.aux,.histfile.*,cmake_install.cmake,*.swap,*.m4,lost+found,.obj,.uic,.hg,*.part,Makefile.am,CVS,*.class,*.moc,*.pc,*.loT,*.po,lzo,CTestTestfile.cmake,.bzr,CMakeTmpQmake,ui_*.h,.pch,CMakeCache.txt,conftest,*.omf,*.vm*

only basic indexing=true

As you can see, I have only basic indexing=true. Yet, when I use Dolphin's Find, I can search for Content. So a name in a cell in LibreOffice Calc is found. Is that normal? I thought that only basic indexing=true would only provide filenames:

Only index Files Names

  [General]
  only basic indexing=true
This will trigger Baloo to only index the filename.

The Calc file I created was way after I had only basic indexing=true in ~/.config/baloofilerc and with a few reboots as well.
