indexTags usage (equal / not equal)

[sephiburp]

Hello there,

I'm new with MinimServer, I use it since a few days and I love it already

I have a custom tag in some of my music files, like 'CUSTOM=dad'.
With minimServer I would like to have two lists :
- dadList : containing only the music with 'CUSTOM=dad'.
- otherList : containing only the music without 'CUSTOM=dad'.

For the first list, I can do it by adding this into indexTags : CUSTOM=dad:dadList
For the second list, I just have no idea how to do it... I tried some stuff like 'CUSTOM!=dad:otherList', 'CUSTOM<>dad:dadList', but no luck.

Well actually I understood that I can add just 'CUSTOM' into indexTags, then I have an automatic indexing based on this tag and I get two lists : 'dad' and '[unknown]'.
But I don't like the name '[unknown]', I'd rather prefer a real name of my own.

Any help is welcome!
