I am trying to search people based on other criteria than those provided by the search api. (support_level to be more specific) I can't seem to find a way to do that. My nation has about 400 000 people in it. Even if I narrow using the tags, I still have to sort through around 80000 people.  With a limit of 100 results per page, that's still 800 requests. Am I missing something? I tried using the custom_value field of the search endpoint but it doesn't seem to work with preset fields in the database like support_level. 

Thanks
