In the documentation it states: ""This will return true and, if a regular expression was provided, the groups defined in that regex for the first matched value it finds in the collection."" How this can be understood? I would appreciate an example.

If I use Regex text field of Inputs, I would expect to have all matches in Groups collection of Outputs. Unfortunately it does not work. Do you know why? Or am I wrongly interpret this output?

Make a collection with Field1 and Field2, give it 4 rows with values A,4 B,3 C,2 and D,1 Use ([2-9]) as the regex for Field2, and the first match will be 4 Change the Field2 values to 1,2,3,4 and the first match will be 2 Mon, 15 Oct 2018 15:34:00 GMT https://community.blueprism.com/t5/Product-Forum/Utility-Collection-Manipulation/m-p/55435#M9774 John__Carter 2018-10-15T15:34:00Z
