SUMMARY When using the filter in Dolphin `Ctrl` + `I`, it should support a simple exclude like many are used to in search, like `-exclude_term`. Example directory: Folder ├── doc2.assets ├── doc2.md ├── doc.assets └── doc.md STEPS TO REPRODUCE 1. Filter: `-*.assets` OBSERVED RESULT Actual: blank results (all items filtered) EXPECTED RESULT Folder ├── doc2.md └── doc.md SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.4.67-1-MANJARO KDE Plasma Version: 5.19.5 KDE Frameworks Version: 5.74.0 Qt Version: 5.15.1 ADDITIONAL INFORMATION This is the form many are already used to from searching with things like Google and would be very nice to support in Dolphin.
Currently the filter bar uses the Qt regex engine which in turn is Perl regexes. This would require switching to another filter engine which supports that kind of syntax.
> This would require switching to another filter engine which supports that kind of syntax. Or could the feature perhaps look like a "mode" for the filter bar, where the same regex engine is being used, but its result are negated?
