Splunk group by value with pattern matching

[msrama5]

I have saved search below FirstQuery which group by values with pattern matching and want to classify anything not falling under regx pattern for APIFamily in "URI "(?APIFamily[/\w.]+/v\d+)/" " to classify as other category in search query 2, Any ideas how to get the values not matching group by in other category ?

FirstQuery -
search environment=test
index=iis* NOT "GET / - 80" NOT "GET / - 443" NOT "/ping*" NOT "swagger"
|eval URI=lower(cs_uri_stem)
|rex field=URI "(?APIFamily[/\w.]+/v\d+)/"

Search Query 2 on FirstQuery
| savedsearch FirstQuery
| search *
| stats count as total, count(eval(sc_status>304)) as errors, count(eval(sc_status<304)) as pass by APIFamily

Can you please repost, and use the tick marks (key above the tab key on US keyboards) around code? This will help readability and prevent the board from stripping content.
