[otrs] Is it okay to add 'robots.txt' in otrs dir without internal search interference?

Hello. Is it okay to add 'robots.txt' in the 'otrs' directory without causing problems with the search features internal to the software when logged in via the admin side or user's side? What I mean is, if I add robots.txt listing all of the subdirectories, I still, of course, need to be able to use the search feature inside of otrs as usual. I don't want search bots to index any of my otrs anything. Thanks in advance.
