Just a boolean filter term will do. When you're indexing with omindex,
then you're probably doing something like:

----------------------------------------------------------------------
$ omindex -p --db /my/db/path --url 'http://www.mysite.com/bob' \
  /var/www/www.mysite.com/bob
----------------------------------------------------------------------

in which case omindex will generate a boolean term Pbob for all
documents created during that index. You then need to have B=Pbob as
an http parameter to omega.cgi when searching, so something like:

----------------------------------------------------------------------
<select name='B'>
  <option vlaue=''>Entire site</option>
  <option value='Pbob'>Bob's bits</option>
  <option value='Pcorporate'>Corporate information</option>
  <option value='Pcheese'>History of cheese</option>
</select>
----------------------------------------------------------------------

should do what you need - I haven't used this recently, but that's one
of the reasons the subsite concept was added to omega.

Cheers,
James
