Create List of strings from the string inputted by the user c#

I have this method:

public List<string> AdvMultiKeySearch(string key)
{
    string[] listKeys = key.Split(',');

    string[] ORsplit;
    List<string> joinedDashKeys = new List<string>();
    List<string> joinedSearchKeys = new List<string>();

    for (int i = 0; i < listKeys.Length; i++)
    {
        ORsplit = listKeys[i].Split('|');
        joinedDashKeys.Add(string.Join(",", ORsplit));
    }

    for (int i = 0; i < joinedDashKeys.Count; i++)
    {
        string[] split = joinedDashKeys[i].Split(',');
        for (int j = 0; j < split.Length; j++)
        {
            joinedSearchKeys.Add(string.Join(",", split[i]));
        }
    }

    return joinedDashKeys;
}

I am trying to create a method that receives a string Keyword that is composed of the words,comas, and '|' character. For example, user enters

glu|sal,1368|1199

And method should produce/return List of strings: "glu,1368", "glu,1199", "sal,1368", "sal,1199"

It's been more than two hours and I still can't figure out how to correctly implement it. Can someone help please?

Given the input above this will show any number of combinations as long as there is one comma.

char[] splitter1 = new char[] { '|' };
char[] splitterComma = new char[] { ',' };
public List<string> AdvMultiKeySearch(string key)
{
    List<string> strings = new List<string>();

    string[] commaSplit = key.Split(splitterComma);
    string[] leftSideSplit = commaSplit[0].Split(splitter1);
    string[] rightSideSplit = commaSplit[1].Split(splitter1);

    for (int l = 0; l < leftSideSplit.Length; l++)
    {
        for (int r = 0; r < rightSideSplit.Length; r++)
        {
            strings.Add(leftSideSplit[l] + "," + rightSideSplit[r]);
        }
    }

    return strings;
}
