hey, loving using zaraz compated to GTM

hey, loving using zaraz compated to GTM -- great concept. But a few questions.
First, what is the regex engine used? i want to identify when a parameter is not empty, so what's the most effective rule? query param Not matches regex

/^$|\s+/

/^$|\s+/

(^$|\s+)

(^$|\s+)

without the /s or just

^$

^$

... or should I use a positive match on something like

(.|\s)*\S(.|\s)*

(.|\s)*\S(.|\s)*

... Will the simple negative matches work if the parameter just doesn't exist, or will the rule fail with an error because the parameter doesn't exist? GTM variables I would look for falsy javascript variables like undefined|NaN... Any guidance?
