Limit Records Number on “Do a Search for” without Constraint

Hi, Bubblers!

I looked for it in the forum but without success.

Anyone know, when we use “Do a Search for” in a Thing and add “:items until #100”, if this runs on Server side or Client Side?

If it is run on the Client side, is there a way to limit the record number after use constraint on “Do a Search for” on the Server side?

Thanks in advance!
