Filter of field type Smart Multi-select

[Stefan Vogt]

Dear all!

It seems i missed something essential and can't google it so far. I got a form containing a field of type Smart Multi-select (refers to a field of another form). Now i want to filter the form's data. Imagine the field of type Smart Multi-select containing "Name", "Colour", "Size".... Now if i filter "Name" i get all data containing "Name". If i filter "Name" and "Colour" i get all data containing either "Name" or "Colour" as well as the datasets containing "Name" and "Colour" and so on. So the arguments of the filter in field type Smart Multi-select are connected by the operator OR. But how it is possible to return after the filtering of "Name" "Colour" only the data that contains "Name" plus "Colour" but e.g. not "Name" and "Size" or just "Name"??

A trial page including the filter can be seen here: https://wiki.tum.de/x/SoGmUg

Thanks in advance for any hint.
