Wildcards for contains segment?
Somehow some of my team's URLs are getting distributed with multiple question marks in them. We have an evar pulling in the entire query string, so I'd like to use that to build a segment based off of that evar to look at this data a bit deeper. However, I'm unsure of how to build a segment that looks for a question mark and then a second question mark later in the evar value.
It seems intuitive to somehow input a wildcard between and after the question marks but I'm not sure if Analytics supports such wildcards?
How would I build this segment? Thank you!
