Does it have any ill side effects when url has multiple collections? Like can it cause expression to compile and run on many nodes at once?
Our scripts generate the url, when we are doing a regular searching on multiple collections, that url is necessary but if it’s ill for streaming ones, I should change them.

This will be where the collection is compiled and run. It has no effect on what is actually being searched. That is specified in the expression themselves.
