disallowing url midway

[defanjos]

I want to be able to stop pages in the format wwww.site.com/xyz/index.php?go=page&id=1234 from being indexed.

Will this work?:

User-agent: *
Disallow: /xyz/index.php?go=

Will the above stop all urls after the "go=" from being indexed?

I still want /xyz/ and /xyz/index.php to be indexed

Thanks in advance

That should work. I have encountered some smaller bots that have problems dealing with urls that contain unusual characters.
