A.- I would also add "nofollow, noarchive" tags [1] to your X-Robots-Tag header:
- "nofollow" -> do not to follow (i.e., crawl) any outgoing links on the page.
- "noarchive" -> prevents Google from showing the Cached link for a page.
B.- I would specify in Search Console (former Webmaster Console) how should Google handle "query" parameter [2]
C.- Prevent those spam searches by blocking source IP address, User-Agents, combinations of both, etc.
Good luck!

A) I'm going to add the nofollow and noarchive to see if that helps the issue.
B) I've already set the search console to ignore the query parameter but I'm still getting new spam results coming in.
C) I've been looking into this but so far the meta information for the spam requests is not consistent and it's tricky to identify so far.
Thanks for the help and the luck, I think I'll need it!
