Is there an easy way to find the exact field name for a custom field when customizing search results? For example a custom field in a form is labeled "Invoice#" but when I need to include it in the search results, that field is actually named "References". I would like to know how to easily find the correct field name to select without the need to contact the admin/person who created the custom field if possible to save time.

Turn on the personal preference "show internal ids"

Yeah it doesn't really solve it..because there are a lot of situations where I'm trying to extract search results with specific custom fields like reference, memo, remarks etc. Problem is if I search the keywords usually there'd be a bunch of similarly named fields and I have to do trial and error to figure out the right one and then find out it's a field with a completely different name. Anyone ever had a similar issue?
