Widen the search results

Previously the search that had a space in it yields no results if the
match is not exact e.g. ``archlinux keyring`` yields no results even
though there is a package ``archlinux-keyring``. This patch modifies the
query to search for ``archlinux AND keyring``, both for package names
and package descriptions. This leads to more search results.
