Hello Team, I have started using Elastic Search recently and trying to build dashboard based on Elastic Search data sets. I’m trying to use **regex** to get the **Jira Key** from one of field within Elastic Search. I could see it works both in the **[regex101.com](http://regex101.com) site** and also when I define a **template Variable** and apply the regex to the field ( ((?=([A-Z]{1,10})-?)[A-Z]±\d+) ), I could see the searched values displayed (refer attached screen shot). ![Screen Shot 2020-04-21 at 1.13.21 PM](https://us1.discourse-cdn.com/grafana/original/2X/0/049c5d513432e96ddc9b5b398db6c882a4d4f543.png) The problem I have is that, when I tried to apply the same regex within a graph panel within the query section, **I’m not getting the search work here**. Tried escaping the unicode characters in the expression as well ( field:/.\*((?=([A-Z]{1,10})-?)[A-Z]+-\d+).\*/g ) but still not working, ![Screen Shot 2020-04-21 at 1.16.37 PM](https://us1.discourse-cdn.com/grafana/original/2X/9/988ef6f63f7f449c721da006787cc86830922b2f.png) Could you please let me whether the regex within a template variable works differently from within a query section of graph panel (Since the data is large within a variable (more than 1024), I need to apply the regex within graph panel to get the count of matching patterns Thanks Sam
