Wildcards to ignore fields

[networkinss]

The expression to ignore fields is not yet 100% clear for "excludeProperties".
It seems on the left side (url of endpoint) you can use a wildcard with ".*" while on the right side
you cannot use that wildcard (instead it makes a ".contains()" check).

So why the dot for the left side ?
Tutorial should make that clear for the right side as well.
