How Does JIRA Handle JQL Functions?

If I have the below JQL, when it runs the function, is it running the function against all issues or just the ones that qualify on the other clause (project = CVA).

project = CVA AND issue in subtask("status != Closed") 


I'm trying to figure out if functions performs better if there is additional clauses, like the example above that is filtering by project.

It is running against all issues. JIRA runs every clause and then does the AND/OR on the result set.Following should perform better!

issue in subtask("status != Closed AND project = CVA")

 

 

By “JIRA runs every clause and then does the AND/OR”, do you mean that the following would return three separate result sets to be analyzed by the query engine: project = “CVA” AND status != closed AND summary ~ “migrate” Or is this how JQL conceptually works, but in truth it has an optimizer that recognizes a more efficient execution plan? Is there a whitepaper or URL that you can reference for more information on how JIRA executes JQL?
