Complex Search with "OR"

[LisaEggert]

I would like to make a quiet complex query with a chain of smaller queries connected with th OR-operator.
In "normal language" it would be something like: "Show me all results that are either A=B and B not= C or D=E and E not=F or G=H and I=K but Hnot= ..."
I used the |-operator and brackets. My first attempt looks like this:
(REISCH = ‎"PAARR‎" &
REILAB &
REILAB &
#1 o #2 &
#1 r #3 &
#2 != #3) |
(REISCH = ‎"KREUZ‎" &
REILAB &
REILAB &
REILAB &
REILAB &
#4 o #5 &
#4 o #6 &
#4 o #7 &
#4 r #8 &
#5 == #7 &
#6 != #8) |
(REISCH = ‎"KREUZ‎" &
REILAB &
REILAB &
REILAB &
REILAB &
#9 o #10 &
#9 o #11 &
#9 o #12 &
#9 r #13 &
#10 != #12 &
#11 == #13) |
(REISCH = ‎"BLOCR‎" &
REILAB &
REILAB &
REILAB &
REILAB &
#14 o #15 &
#14 o #16 &
#14 o #17 &
#14 r #18 &
#15 == #18 &
#16 != #17) |
(REISCH = ‎"BLOCR‎" &
REILAB &
REILAB &
REILAB &
REILAB &
#19 o #20 &
#19 o #21 &
#19 o #22 &
#19 r #23 &
#20 != #23 &
#21 == #22)
I probably do not understand the query-language properly - being a literary sholar. Is there any possibility to make such a query? In the guidelines available I can't find much on complex queries of this kind.
Thank you very much!
