i'm trying to find records where a multi-select field doesn't have any items selected in it ... and none of the options I've tried are working (noneof "none" for example). what is the trick to this?

anyof none

i'm sorry. I mis-wrote my question. I'm trying to find records where the multi-select field is NOT empty. In other words, at least one option is selected.

I tried that today and it wasn’t working in a script search. Had to revert to anyof and select all values lol

yes ... it just seems hard to believe that there is no way to do t his correctly

Well I tried and really Cba to raise a support ticket due to it not working properly

["NOT",["custrecord_my_multiselect","anyof","@NONE@"]]

In the UI, I've used a text formula, e.g.

{multi_select_field_id}

with the 'is not empty' filter. For a scripted search I like @battk’s solution, especially if you're already using filter expressions instead of Search.Filter objects.
