When a lookup field is added to a custom module to lookup records from another custom module what does the search box actually search on in the records of the custom module being looked up? I believe it is just the email field but my testing has rendered all sorts of inconsistent results and email being the only consistent one to search by. I.e. if I search by the First Name (custom single line text field in the second custom modile) it pulls back half the records with that name and not all. First name is a field in the default view of that module.

i can’t find anything in the documentation that describes what the lookup field searches for in the related modules when searching using the magnifying glass on the lookup field
