problem with creating virtual libraries

[u532]

i tried to find a solution in the manual and googled it but couldn't find proper answers.

i am trying to create 4 separate virtual libraries:

1. Discworld (containing all english books from the series discworld, obviously)
2. Scheibenwelt (containing all GERMAN discworld books)
3. Deutsch (containing all other german books THAT ARE NOT FROM THE SCHEIBENWELT SERIES)
4. Englisch (containing all other english books THAT ARE NOT FROM THE DISCWORLD SERIES)

creating the first two libraries wasn't hard, i simply used the search expression

series:"=Discworld"
and
series:"=Scheibenwelt"

but i don't know how to get those two series out of my other two collections.
first of all i don't know how to use more than one expressions when creating a library, i tried separating them with semicolon and comma but it didn't work. newline or whitespace can not be entered.
the first expression for the language, e.g.
language:"=deutsch"

the second (and third) expression for filtering out the discworld and scheibenwelt books from all the others. but here is my other problem, i don't know how to tell calibre "unequal"
i tried

series:"!=Discworld"
//the != standing for EQUALS NOT or IS NOT
but it didnt work either



it would really appreciate your help!



btw: i'm using calibre 1.30 in german on win7

cheers

sry for bothering you with my stupid question, i just found out myself:

"deutsch" and not "scheibenwelt"
or
"englisch" and not "discworld"

those expressions work. i was just overthinking it with all the unequal expressions and what not.
