btw, in your example, you use: 'package_id:12345' maybe instead of the package_id, include/evaluate context for the entire url for the equivalent of google's site:example.com/subsite/application/page. Google accepts a url as part of the site constraint. For example, to search just the openacs docbook docs for version 5.2, include: site:openacs.org/doc/openacs-5-2/
