Does a Global Expression search run without constraints before its parameter is defined?

Need help

Hi everyone,

I have a question about Global Expressions in Bubble.

Can I use a parameter from the same Global Expression as a constraint in a Do a search for... expression inside that Global Expression?

For example, if the Global Expression has a parameter called Selected Exam, can I use that parameter to filter the search?

My main concern is about WU/performance.

Does Bubble wait until the parameter has a value before running the search with the constraint, or does it first run the search without the constraint and then filter the results once the parameter is loaded in the app?

Thanks in advance.
