Filter reverse

Hello

I would like to know, if there is a way to reverse filter search? That would work not like reverse selection?

This is what I mean:

1] I load all the files into Mp3tag
2] I put into filter "ABC"
3] I see a list of files which have "ABC" in theirs TAGS and FILENAMES
4] I reverse the search
5] Now I see all the files except those witch "ABC"

And by "ABC" I mean any kind of signs [which I don't want to specify and I don't want to precise their localization]

Is this doable, the step number 4? Maybe by some action? Or would it have to be precised [not general so general] so I would have to know what exactly I'm [not] looking for?

See there ...
http://help.mp3tag.de/main_filter.html
... there is an example how to invert a filter expression.

I have a file with "ABC XXX" title

So to single it out I can:
1] write in filter field expression
title IS "ABC XXX"
title IS ABC XXX

2] write in filter field simply the whole title
"ABC XXX"
ABC XXX

3] write in filter field shortened title
ABC

But to single it out I can't
4] write in filter field expression with shortened title
title IS "ABC"
title IS ABC

Now to reverse that search I can:
5] write in filter field expression
NOT title IS "ABC XXX"
NOT title IS ABC XXX

But now to reverse that search I can't:
6] write in filter field expression
NOT "ABC XXX"
NOT ABC

So there is no easy [quick and universal] way to reverse? I have to specify what field exactly I am filtering and know the exact value [in this case the title]? Or am I missing something from the manual? [This is why I asked- I've already red that on-line help]

And the [very effective but also very long] workaround would be to:
A] load all the files
B] find what I'm not looking for, by whatever means
C] select findings and put something like >> !this is not it! << in some normally not used tag and save the change
D] load all the files again
E] search via filter for >> !this is not it! << [with no need of using the quote signs]
F] remove all found files with "!this is not it!" tag
G] remove from filter "!this is not it!"
H] do whatever is needed to be done
I] load all the files again
J] in all of files clear the tag field bearing the >> !this is not it! << value
?

[Which is time and steps consuming, but can easily add up multiple different findings of what I'm not looking for, by repeating steps "B" & "C", before going to "D"]

This is a simple example to demonstrate the principle ...
Filter: TITLE HAS "ou"
Inverted Filter: NOT TITLE HAS "ou"

It would be so much better, if one could just write in filter

HAS "ABC"

and to reverse it

NOT HAS "ABC"

without specifying the tag field

Or even better: just click an icon, that would automatically reverse whatever expression is in the filter, no matter how complicated. I think, such a handy feature should be implemented in future versions of Mp3tag

  • HAS "ABC"
    NOT * HAS "ABC"

Yes, that works and saves time in simple cases

Thank you for the info
