Restrict the result set of the search autocomplete results to:
Precise and above charms. Oneiric is well past EOL and many Oneiric charms do not meet our current standards.
Only a single most relevant charm to the user per name ex) only one mysql charm, closest matching series and recommended status.
Any others up to 5, including bundles appended to the end after the above filters.
