Sort not working by " \| "

[AViktorovGRSE]

We have some items in a db. If we will use for sorting "\|" it will not work. At the result we will get all items from the db.
Example: item1: Cat1\| , item2:Cat2
Sorting by:\|
Result: Cat1\| , Cat2
Expected value: Cat1\|

why in sorting do you expect to filter the result?

you should use a filter instead of sorting!
sorting gets a parameter name to sort it based on type (number or string or ...) ascending or descending :)
