   * `close_on_execute` By default set to false. Closes angrysearch after opening a file or a path in a file manager
   * `conditional_mounts_for_autoupdate` By default empty. Purpose is to hold mount points that should be present when the database is being updated. If a mount is missing, automatic update through crontab will not run, but use system notification dialog to inform that paths set in this settings are not mounted. This prevents overwriting the database when not all drives are present. Values are system mount points, space separated.
   * `darktheme` By default set to false. If set true dark theme is used for the applications interface, as defined in the qdarkstylesheet.qss, also resource_file.py contains icons for dark theme
-  *   `directories_excluded` By default empty. Which directories to be ignored, directory names(no slashes) separated by space are valid value there. Can be set through program's interface, in the update window. Directory `/proc` is hard coded to be ignored
+  *   `directories_excluded` By default empty. Which directories to be ignored. Just name of the directory will ignore every directory of that name, full path like `/var/cache/pacman/pkg/` ignores exactly that single folder, or parent/target for more easily targeting specific folder `pacman/pkg`. Can be set through program's interface, in the update window. Directory `/proc` is hard coded to be ignored
   *   `fast_search_but_no_substring` By default set to true. It holds the last set value of the checkbox affecting the speed of search and substrings, see FTS4 in the section above
   *   `file_manager` By default empty. Whatever application/script is put there, it receives the path when the path column is double-clicked. If left empty angrysearch will try to autodetect default file manager using xdg-utils. If one of the following file managers are set/detected: ['dolphin', 'nemo', 'nautilus', 'doublecmd'], the behavior will change slightly, sending to those file managers full path to the file, highlighting the target file when opened in a file manager.
   *   `fm_path_doubleclick_selects` By default set to false. Needs `xdotool` package, and preferably manually set file manager in config. When set to true, Thunar, PCmanFM and SpaceFM file managers will be able to open containing directory with the file selected
