Companies api, search modified newer

https://developer.copper.com/companies/list-companies-search.html

shows that i can list by:

• age
• minimum_created_date
• maximum_created_date

I’m not clear what age is.

I’m looking to see rcompany ecords modified since (e.g. 1 day ago). There is a field `'date_modified'` in the companies record. But, there is not a min/max updated date in the doc.

Now, it appears that minimum_modified_date *does* work in the query, is this just an oversight in the doc?
