Advanced search on a multi-select field, possible ?

Advanced search on a multi-select field, possible ?

Hi,

We have a multi-select field as custom field for our customer. I'm trying to look for customer having a specific entry in the that field. But in the advanced search panel, I can't find this multi select field (under the "Show More" section)

How can I search for customer using that field ?

(yes, the field is active)

Regards,

Olivier
