If you have some rust projects, don't forget to run this:

balooctl6 config add excludeFilters target

to exclude the rust target directories from the file index.

each one contains thouthands of files and even having a couple of projects explodes file index size into hundreds of megabytes and makes the indexer get stuck, sometimes for hours, without doing this.

you may have to purge the index and re-index everything for the changes to take into effect sometimes:

 balooctl6 purge
 balooctl6 resume

(also i believe this should be the default)
