Item8501: Strange sorting with FilterPlugin

What are the dependencies, that the following code renders correctly?

%MAKEINDEX{"Anlage;Anlage, Anlage (Beschreibung);AnlageBescreibung, Anlage (Handbuch);AnlageHandbuch" cols="2" split="," header="Demo" pattern="(.*);(.*)" format="[[$2][$1]]"}%

Why am I asking? So, on our installation the list looks as following:

Not a bug. The brackets are used to mark the substring to sort the index. Add explicit brackets to fix accidental sorting when the first element might have brackets for some reason.

Try

%MAKEINDEX{
  "Anlage;(Anlag), AnlageBescreibung;(Anlage (Beschreibung)), AnlageHandbuch;(Anlage (Handbuch))" 
  cols="2" 
  split="," 
  header="Demo"
  pattern="(.*);(.*)"
  format="[[$1][$2]]"
}%

Best practice is to make the first group $1 the topic name by default and then pick the sortable string using brackets.

Thanks for the answer. But on our wiki, the brackets remain in the title. Shouldn't the pattern look like following?

  pattern="(.*);\((.*)\)"

Wouldn't it be easier to offer a parameter disabling the some what obscure function of 'brackets/substring order'?
