Case sensitivity not honored in Regex
On filtering report with a regex to differentiate between lower and upper case characters, the results are not as expected. That is [a-z] and [A-Z] are not considered as different regex.
What should be done in such a case?
Re: Case sensitivity not honored in Regex
Typically it's not a best practice to have mixed cases anywhere but page titles. I suggest lowercase filters for campaign medium, campaign source and request URI in your analysis views (keep an unfiltered view).
That said, it doesn't help you now with your historical data. The only place you can use case sensitivity is in View filters by ticking the checkbox.
It's kludgy, but you can always download to Excel and filter there.
