@john-ingebrigtson To the best of my knowledge, it only searches core fields, and does NOT search custom fields. 

I would like to learn more about how many additional fields you need to search? And what are their associated data types? 

I am wondering: if phone numbers are a data type, and if we can detect the field’s type, then it is possible we could search these fields automatically. 

But this would need to be added to our roadmap.
