Problem:
I used "Post fields" rather than "User fields" and I'm having second thoughts. Should I use "User fields" for the profiles, which will be displayed and on an archive?
I need to make 3 different types of user profiles and want to be sure I'm doing this correctly before going further. All 3 profiles will be displayed and will have a search page (archive of users).
Side note: If it's better to use "user fields" for profiles, is there an easy way to move the custom fields from Post Fields to User Fields?
Solution:
User view does not support custom search form, so in your case, if you need to search on those fields, it is not recommended to move the custom fields from Post Fields to User Fields.
For example, you can create a normal user view, query wordpress user, should be able to see the message:
Only Views listing posts can have custom search inputs.
And since the post fields and user fields are stored in different database table: wp_usermeta, wp_postmeta.
So there isn't a easy way to move the custom fields from Post Fields to User Fields, you will need to setup them manually.
