We're not apache experts by any means, so you'll almost certainly be better off asking in a dedicated forum.

Yes, and probably in a number of different ways.

If you mean /search is omega and /nagios is nagios, then you can still do this within a virtual host. (I'm confused by what you say in general here, and this is exactly the situation virtual hosts are designed to support: multiple websites with different hostnames served from the same machine on the same port.)

Omega returns URLs that are based on the configuration and way you run omindex. It's intended to provide searchable access to a website that's (largely) served statically, such as by apache using a DocumentRoot, but if you make use of aliases omindex can support that as well. One way in this particular case would be to Alias /docs to somewhere, and re-index with those as the base URL and WEBPATH respectively to omindex:

omindex --db DBPATH --url /docs PATH-TO-DOCS-ON-DISK

(as at the top of http://xapian.org/docs/omega/quickstart.html)

Omega doesn't 'look' for the files anywhere, it just constructs URLs. So you need to configure the web server to serve them from somewhere.

Yes, Alias is only allowed in server config & virtual hosts (http://httpd.apache.org/docs/1.3/mod/mod_alias.html#alias). I strongly recommend you seek apache-specific help here to achieve what you need to do.
