index = listview.findItem(strMultiText, strSeparator);
Searches for the specified item and returns its index or -1 if no such item exists. The values for each column to search are specified in the strMultiText string, separated by strSeparator. Each one of the strings can contain regular expressions.
// Test findItem with regular expressions
var index = ListView.newItem("A first string|A second string");
if (index != ListView.findItem("\\.*|\\.*second.*"))
Env.LogError("Could not find the new item");
