Search/List Custom variable

i was looking for a way to filter visitors log by custom variables (as search fo ip address explained in 301 Moved Permanently )

Can you help me?
I’ve already read topic 301 Moved Permanently but it doesen’t seems to work.

I have to search for custom variable “nlReferrer” value ""


you can use the “widget” view (go to WIDGET link), then add the same parameter as you would for the API request, documented in Segmentation - Compare segments of visitors - Analytics Platform - Matomo
