separately and multiple fields may be queried too. Lots of search
strategies are available. A set of fields and search strategies may
very depending on your server configuration. For example, you can
search in binary (pkg_summary.gz generated by pkg_info -X) or source
(pkg_src_summary.gz generated by wip/pkg_src_summary) repositories.
