SearchRequest/Organization doesn't return all the fields

I'm pretty new to this, so please forgive any terms I use incorrectly.

According to the SKY API reference page, both the GetRequest and SearchRequest endpoints should return the same JSON structure. In my testing, GetRequest does match the documentation. SearchRequest, however, does not include the coding fields or custom fields. The same holds true for the related organization endpoints.

Am I doing something incorrectly? Or is there a flaw in the output?
