Rule resolution process-What is a qualifier in rule resolution?

In Rule Resolution topic (The Rule resolution process | Pega Academy), i came across this line:
“Pega Platform moves to the next Rule in the list. The next Rule candidate does not have a qualifier, so the system selects this Rule.”

and in the images also I find the term qualifier. What does that actually mean? When i googled, I found only property qualifiers I did not get anything like qualifier for the rule.

Hi @SubhashK7107: Qualifier referred to the specific academy module refers to the Rule Circumstance. You can get to know about Circumstancing a rule from the previous module here.

Thanks.

@ArulDevan Thanks for the clarification. Since there was another rule version with date circumstancing i got confused.

@SubhashK7107 In the module the qualifier refers to the condition for the circumstance rule version. It can a date or a condition based on a property. Doesn’t have a qualifier means it is the base version

@kammv Thank you.
