So my question on the double escape, is there no way to handle that so the user can use single escaped regex? I know many folks who use big data platform to test large complex regexes for things like security appliances, and having to convert the regex seems like a lot of work if you consider every user has to do that. If there was a way to do it in Drill, that would save countless people hours and save many mistakes.
