@Shawn Talbert I remember writing a wrapper around that because of the inability to find duplicates(multiple results) and not sure about that 10k limit but I think if you can loop pass 10k lines with record line count it should also find value.

Thanks - I am wondering if that function does a search behind the scenes in server script or if it just loops over lines just like we could otherwise do in SuiteScript?

I'm not sure, my educated guess is it does the same as looping over the lines.

that would be a bummer, as I think looping is limited to the 10k limit (i.e. IIRC getting the line count will never be > 10000 from suitescript)
