I have a scheduled script that's running against a saved search. There's a lot of data in that search, say 5000. If I set the "Max Results" under the results tab to 20, would my scheduled script respect this? Meaning, will it only process the 20 rows?

Never tried but I doubt it

I was able to test this by filtering on 2 rows in the search then set the Max to 1. After running the script, it processed both rows, so it didn't do what I had hoped.
