Find using an Evaluator column based off a script column

I've not been successful in making this work with a script-added column. Am I doing something wrong? Here's what I mean. I define a simple evaluator column like this

this gives me the following. All good so far.

but when click Find to look for the number '1' it finds nothing. If I use another field in my Evauator column such as 'desc' then it works and Find correctly gives me test1 in the results.

What I'm trying to do is use Evaluator functions to pull certain information out of this script column and then search within that information. Hope this makes some sort of sense. Thanks.

My guess is that it is because the way you're searching does not allow partial matches.
Try using instead:
=InStr(Val("eval:DescriptionX"),"1")!=-1

Still doesn't find anything, but thank you.

Try *1*.

Thanks, but nothing found.

* works and it filters.

I tried my file index evaluator column.
Same result with my dir index evaluator column.
Find was unable to find specific values, but could find * .
Using my early Dopus 13 release photo Field of View Column I found that * limited the find to photos.

Edit Note: The find was limited to photos that actually have FOV metadata.
